The current set of Javascript linting rules that we're using in this
project is outdated, and it has lead to a variety of competing styles
in the Javascript codebase.
Update the project's linting rules to match those provided by the latest
release of eslint-config-airbnb, but disable a bunch of rules that
aren't compatible with this project.
I've split this change into two commits. The first commit contains the
manual changes that I made to satisfy the new rules, and the second
commit contains all of the whitespace, quoting and commas changes that
were fixed automatically by eslint.

This PR updates `react` and `react-dom` to version 16.11.0, and `react-router`
and `react-router-dom` to version 5.1.2.
The following breaking changes have been fixed as part of the upgrade:
- Change deprecated `componentWillUpdate` to `componentDidUpdate`
- Replace`react-url-query` library with `use-query-params` (a Hook) due
to the deprecation of some React lifecycle methods. This required some
changes in the Tap, Top, TapQueryForm and TopRoutes components.

* Avoid the dashboard requesting stats when not needed
Create an alternative to `urlsForResource` called
`urlsForResourceNoStats` that makes use of the `skip_stats` parameter in
the stats API (created in #1871) that doesn't query Prometheus when not needed.
When testing using the dashboard looking at the linkerd namespace,
queries per second went down from 2874 to 2756, a 4% decrease.

### Motivation
PR #3167 introduced the tap APIService and migrated `linkerd tap` to use it.
Subsequent PRs (#3186 and #3187) updated `linkerd top` and `linkerd profile
--tap` to use the tap APIService. This PR moves the web's Go server to now also
use the tap APIService instead of the public API. It also ensures an error
banner is shown to the user when unauthorized taps fail via `linkerd top`
command in *Overview* and *Top*, and `linkerd tap` command in *Tap*.
### Details
The majority of these changes are focused around piping through the HTTP error
that occurs and making sure the error banner generated displays the error
message explaining to view the tap RBAC docs.
`httpError` is now public (`HTTPError`) and the error message generated is short
enough to fit in a control frame (explained [here](https://github.com/linkerd/linkerd2/blob/kleimkuhler%2Fweb-tap-apiserver/web/srv/api_handlers.go#L173-L175)).
### Testing
The error we are testing for only occurs when the linkerd-web service account is
not authorzied to tap resources. Unforutnately that is not the case on Docker
For Mac (assuming that is what you use locally), so you'll need to test on a
different cluster. I chose a GKE cluster made through the GKE console--not made
through cluster-utils because it adds cluster-admin.
Checkout the branch locally and `bin/docker-build` or `ares-build` if you have
it setup. It should produce a linkerd with the version `git-04e61786`. I have
already pushed the dependent components, so you won't need to `bin/docker-push
git-04e61786`.
Install linkerd on this GKE cluster and try to run `tap` or `top` commands via
the web. You should see the following errors:

Imports lodash function individually, eliminate 'import _ from lodash'
This branch replaces imports of all of lodash (import _ from 'lodash' with per
function imports e..g import _isNil from 'lodash/isNil'. This reduces the bundle
size from~520 kb to ~160kb.
I've also taken the opportunity to replace our use of lodash functions with
native js functions where it makes sense (e.g. some maps, concats, sizes).
Now that #1921 has merged, we can query for top routes for any resource,
not just services.
This PR adds a dropdown for all resources to the Top Routes query form.
It also adds a link to the Top Routes page in the sidebar.
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.
Switch the dashboard's component library from antd to material-ui.
There are extensive changes to most of the frontend components in the app.
This branch changes all uses of antd components to their closest equivalent in
material. There is still a lot of polish that needs to go into the look of
individual components, but since the major component rewrites are done, I think
get this work in so that further work can be done in smaller branches.
Changes in this branch:
- add Material-UI 3.2.2 to the project
- replace all uses of antd with material-ui components
- remove antd from the project
- slight modifications of eslint rules
- restructuring of app components to be rendered under the Navigation
component
- deleted most of our css (replaced with material's inline styles)
- pinned package versions in package.json (mostly removing ^)

Fix a react key error when there were multiple unmeshed upstreams

Fix key error in autocomplete dropdown
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.
The solution is to suppress 1006 errors that occur in the web browser since the connection is closed anyway. There is no negative side effect that occurs when the connection is closed abnormally and so the error message is benign.

Consolidate the source and destination columns into one column,
and add a direction column (To/From) so the user knows if the
displayed resource is src/dst.
The web client displays `Websocket [code]` on websocket close errors.
Modify the web client to render a more helpful error message to the
user. If a reason is present, render that, otherwise translate the
websocket error code into a message.

This PR adds a breadcrumb style navigation to the Linkerd dashboard. Each "crumb" links to its corresponding page in the UI.
This PR also includes a small UI fix in the sidebar. The select box always seems to revert to the All Namespaces option whenever there is a state change on the React side. The fix ensures that the select box always displays the namespace filter if it is available and revert to All Namespaces when no namespace is selected.

- Use an ant Select instead of Autocomplete for resource list, so that the user
can see all available tappable resources
- Fix bug where the authority autocomplete wasn't showing any options
- Adds "namespace/" as an option in the resource selection dropdown
This required some weird handling because we allow requests of the form
linkerd tap namespace/linkerd (taps namespace linkerd)
but not
linkerd tap namespace --namespace linkerd (does not work as intended,
taps every namespace)
Increase the MaxRps on the tap server to 100 RPS.
The max RPS for tap/top was increased in for the CLI #1531, but we were

A bunch of small items.
This branch:
- filters out un-meshed resources from the Tap and Top autocompletes
- removes an un-rendered title attribute from the sidebar menu items
- formats latency in Tap with a comma
- prevents the grafana link from showing if there are 0 pods in a deployment
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.
Add a Top page to the linkerd web UI. This is the web equivalent of #1435.
I've used the same fields as in the current implementation.
This branch also includes some slight refactors to the Tap code to enable code reuse.
The request processing logic is pretty similar to that in Tap.jsx, except that we can
immediately discard the result once we receive the response end and aggregate
that result into the top results. So the index of tap results will tend to be smaller
(unless they're long running requests like streaming). But we also add a similar
index of aggregated Top results, and discard oldest results if top has been
running for a long time.
* Add a Top page to the web UI
* Refactor Tap event parsing into common util code
* Small refactors to the TapQueryForm and the CliCmd display to accomodate Top
* Collate tap events based on the ID (src, dst, stream)
* Also refactor keying of req/rsp/end into requestInit/responseInit/responseEnd for clarity
* Use pod labels when present in top
* Fix bug where src/dst were switched in the Tap display table
Tap.jsx is really large and contains a lot of logic that pertains only to the Tap Query Form.
This PR tries to separate the concerns of the form and the query display from the main
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
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
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.
