[web UI] Previously, we were specifying the display order to display the cli flags in the
QueryToCliCmd module. But this order is pretty standard for each command, and
I'd like to avoid hardcoding that list everywhere.
Move the handling of order into the QueryToCliCmd module.
Adds an endpoint, at /profiles/new that allows you to input a service name and
namespace, and download a service profile yaml template.
This will enable future work, where we can add more of the yaml customization via
a form in the dashboard, and use that data to help the user configure routes.
This change alters the controller's Tap service to include route labels
when translating tap events, modifies the public API to include route
metadata in responses, and modifies the tap CLI command to include
rt_ labels in tap output (when -o wide is used).
Previously, we were passing in "tap" as the command name for both the tap and
top forms, resulting in the equivalent CLI command always being linkerd tap
regardless of whether you were in the Tap or Top view.
Fix this to correctly pass in tap or top depending on the page.
The `--open-api` flag is an alternative to the `--template` flag for the `linkerd profile` command. It reads an OpenAPI specification file (also called a swagger file) and uses it to generate a corresponding service profile.

Separates out the querying and table display of route data, so that this module
can be easily placed in other places in the UI.
Adds usability improvements to the routes query form at /routes:
- displays CLI equivalent
- adds dropdown with populated options for service / namespace
As part of this work, made TapQueryCliCmd more generic, so it can work
for other CLI commands besides tap/top.
Adds a (currently not displayed in sidebar, but available at /routes) page to
mirror the current functionality of `linkerd routes <service>`. So far, this is just a
barebones form and table, but it works.
Adds a /api/routes path and handler to the api to receive TopRoutes requests from the web.
Add a barebones ListServices endpoint, in support of autocomplete for services.
As we develop service profiles, this endpoint could probably be used to describe
more aspects of services (like, if there were some way to check whether a
service profile was enabled or not).
Accessible from the web UI via http://localhost:8084/api/services
Add a routes command which displays per-route stats for services that have service profiles defined.
This change has three parts:
* A new public-api RPC called `TopRoutes` which serves per-route stat data about a service
* An implementation of TopRoutes in the public-api service. This implementation reads per-route data from Prometheus. This is very similar to how the StatSummaries RPC and much of the code was able to be refactored and shared.
* A new CLI command called `routes` which displays the per-route data in a tabular or json format. This is very similar to the `stat` command and much of the code was able to be refactored and shared.
Note that as of the currently targeted proxy version, only outbound route stats are supported so the `--from` flag must be included in order to see data. This restriction will be lifted in an upcoming change once we add support for inbound route stats as well.

A container called `proxy-api` runs in the Linkerd2 controller pod. This container listens on port 8086 and serves the proxy-api but does nothing other than forward gRPC requests to the destination container which listens on port 8089.
We remove the proxy-api container altogether and change the destination container to listen on port 8086 instead of 8089. The result is that clients still use the proxy-api by connecting to `proxy-api.<ns>.svc.cluster.local:8086` but the controller has one fewer containers. This results in a simpler system that is easier to reason about.

Draw customizable SVG paths for octopus arms.
This also combines all the unmeshed resources into a list and displays them in
one resource box, instead of adding one box per unmeshed resource. This helps
keep the box heights constant, which I want to draw the arrows.
When a resource has no tap events being streamed to the Tap UI, and a user hits the "Stop" button in the Tap page, the tap stream is left open due to the WebSocket connection not being closed.
It looks like the web server's tap client that is created to stream events from the tap server blocks the main request thread in the web server. This causes the web server to stop receiving any subsequent close frames from the UI i.e. when the "Stop" button is clicked.
This PR moves the tapClient initialization code to a separate goroutine, specifically, the goroutine that reads tap events from the incoming grpc tap stream. This allows the main thread to continue reading messages from the WebSocket connection and allow it to receive close frames.

If you go to /top and select a namespace and then a resource, and then clear the
resource, there would be a javascript error that would cause the whole app not
to render. Fix this.
Problem
Previously, we'd display one row in top per sourcePod -> dstPod. When
viewing resources at a higher level though (e.g. deployments with multiple pods)
the src/dst column displays the resource at that level, and displaying multiple
rows with deploy/foo is confusing.
Solution
Key the top table off of the resource currently being requested, so
that all the rows are rolled up appropriately. In the popover for that column,
display a list of pods/ips that are rolled up.
This branch also adds a generic list of resources to the tap/top dropdown (you
were always able to tap them, but when I switched from autocomplete to select
for this dropdown, you lost the ability to type in arbitrary resources).
If you select a from namespace and from resource in /tap and try to clear them
using the little x in the form field, there would be a huge js error causing the
app to not render. Fix this.
Also removes filterOptions which wasn't being used any more. This will probably
make parsing tap results ever so slightly faster as we're now not trying to also
aggregate potential filter options.
* Fix js errors on Tap form when Clear button is hit
* Remove filter options code since we're not using the filters anywhere
When a websocket connection is closed between Chrome and a server, we get a 1006 error code signifying abnormal closure of the websocket connection. It seems as if we only get this error on Chrome web clients. Firefox and Safari do not encounter this issue.

There are two variables we use to control the volume of Top output,
maxRowsToDisplay, which controls how many rows are in the table, and
maxRowsToStore, which controls the size of the event index we keep in memory for
aggregating results.
Previously, we were only keeping in index maxRowsToDisplay rows, which for the
Resource Detail page was 10 (which is really small for high traffic rest-y
resource traffic - it causes rows to be deleted from the index too soon, and
then causes the data in the table to change a lot). Change this to store
maxRowsToStore rows, and also bump this to 50. This allows us to store results
for longer, and also ensures more consistent data over time.
Another fix for the appearance of the Top columns is to add fixed widths to the
metrics. This will prevent the table from wobbling from side to side.

_.throttle setState for receiving websocket tap events to prevent continuous rerendering
Problem
We receive a lot of websocket events from the tap server. Previously, we
were processing each event as we received it, then calling setState after
processing to update the tables. Each call to setState triggered a re-render of
the whole table. We were rerendering multiplie times a second, causing the whole
page to become unresponsive.
Solution
Throttle setState for receiving websocket tap events to prevent
continuous rerendering. Store the tap events in an index outside of state, and
only update the state once every specified interval (currently 500ms).
We can now view entire namespaces with Top and the page won't crash!
To verify: Go to /top and try topping a namespace

Includes a substantial refactor of Top.jsx to move the websocket
and top-request-aggregation code into a self-contained module
so that this code can be shared by /top and by each resource
detail page.
(This refactor also helps separate concerns in that
page; since that page also makes 10 second requests to the stat
api to populate the autocompletes in the form).
The TopModule uses the startTap prop to figure out whether it
should start a websocket connection and make a tap request
when mounted. (This is because the resource detail pages
start tapping immediately upon load, whereas /top can only
start once you've entered a query.
I've removed the spinner and the awaitingWebSocketConnection
state field because that now belongs in the top module. I think a
similar refactor of tap would be good before we re-add it.

The request processing logic is pretty similar to that in Tap.jsx, except that we can

index of aggregated Top results, and discard oldest results if top has been
running for a long time.

Tap querying and rendering logic.
This will also allow us to easily reuse this form/CLI formatting for the Top page.
Changes in this PR:
* moves all the code for the form into its own component (TapQueryForm)
* moves the code that displays the current query into its own component (TapQueryCliCmd)
* formats the current tap query as the equivalent command line format that you
can paste into a terminal
Now that we have source metadata in tap events, we can display
the pod name in the UI instead of the IP. I've also added a popover
that shows deploy and pod info if we have it.
Also adds another table in the expanded row view to show all the
metadata we have. This table probably won't stick around forever,
but I'm just displaying all the data we have right now.
We have a new format for displaying errors in ErrorBanner.
When a websocket error occurred, we'd pass in text where ErrorBanner
expects and object. This PR puts the websocket errors in an object
Also clean up the display of the error by removing redundant text.
Problem:
We depend on the websocketRequestSent bool (renamed to
tapRequestInProgress in this branch) to determine whether the
start/stop button says start or stop. However, we don't change
this value in setState until we open the websocket connection
(which could take some time). This led to a delay in when you
press the Start button and when it changes colour.
Solution:
Set the state before waiting for the websocket to open, so the
button colour changes immediately and the form feels more responsive

Problem:
Currently the web UI's resource autocomplete also lists authorities.
However you can't tap authorities in this way, you have to use --authority
in addition to whatever resource you're trying to tap.
The web UI is confusing as it presents authorities in that list.
Those authorities should instead be moved to the Authority box in the advanced filter form.
Solution:
* Don't present authorities as options in the Resource dropdowns
* Add authority autocomplete to authority form input
Follow up to @kl in #1391 there is an error when we try to tap an authority
Add client side filtering to the tap table, so that we can narrow down
queries while still tapping a whole resource.
There are two general kinds of filters here:
- filters where the number of possible values is bounded/small and
we know them (e.g. inbound/outbound, grpc status). here, I've tried to
hardcode the list of possible options with explanations (see the GRPC status filters)
- filters where the number of possible values can be very large (e.g. paths)
here, I've generated the list of options as we process the incoming data.
I also periodically delete the oldest filter option so the list of filters
doesn't grow unbounded
Filters added:
- GRPC status code filters
- http status filters
- path filters
- scheme filters
- tls, destination and source filters
* Make use of the Web UI to render tap events in a table
- Return JSON tap events instead of the command line output
- Experiment with a different way of rendering the EventList
- changed the default width back to 100% of the screen because this
table does not look great squished
* Update ant to 3.7.2
* Add autocomplete of namespaces/resources to Tap in web ui
* Add form fields for authority/path/method/rps/scheme
* Add the ability to clear error messages to the error banner
* Add error listener to ws object
Speed up incremental rebuilds by avoiding relinking the controller
and/or web executables when changes are made to unrelated files.
Before this change, any time the git tag changed, the executables
would have to be rebuilt (relinked at least), even if no Go files
changed.
Validated by running the integration tests.

Adds a tap endpoint in the web api that communicates with the dashboard
via websockets.
I've moved a bunch of code from the cli tap.go into utils so that the code
can be shared between web and CLI. I think we should consider making the
display more suited to web, but in the short term, reusing the CLI's
rendering of tap events works.
Adds a Tap page in the Web UI that you can use to make tap requests.
The form currently only allows you to enter a resource and namespace,
other filters coming in a follow-up branch.

`-installsuffix cgo` isn't necessary as of Go 1.10 (where build caching
changed substantially) and it probably wasn't necessary earlier.

This PR adjusts the colour of a popup in the sidebar, as well as removes
references to conduit in the frontend test fixtures.
All that's left in the Web UI code now is a few references to the conduit sites / githubs,
as well as the CLI name.
* Remove a touch of conduit blue from the sidebar popup
* Remove minor references to conduit throughout the web code
* Fully colour the sidebar in new bg colour
This PR begins to migrate Conduit to Linkerd2:
* The proxy has been completely removed from this repo, and is now located at
github.com/linkerd/linkerd2-proxy.
* A `Dockerfile-proxy` has been added to fetch the most-recently published proxy
binary from build.l5d.io.
* Proxy-specific protobuf bindings have been moved to
github.com/linkerd/linkerd2-proxy-api.
* All docker images now use the gcr.io/linkerd-io registry.
* `inject` now uses `LINKERD2_PROXY_` environment variables
* Go paths have been updated to reflect the new (future) repo location.
This PR starts removing all references to the word "Conduit" in the web UI.
In the interest of not making huge changes all at once, I'll gradually start moving away
from the usage of "conduit" in the Web UI. For example, there are a lot of components that
have conduit in their names but they don't need to.
This branch is mostly component / variable names. There should be no visible changes except
the spinner is no longer a Conduit spinner.
See #1262 for visible branding changes.
- Rename ConduitLink to PrefixedLink
- Remove ConduitSpinner in favour of antd.Spin
- Remove css classnames that are conduit- centered
- Parameterize the current Product Name so that it's easier to change in the future
