@rmars and I set out to replace all instances of lodash filter with native
filter in order to prevent the additional import. However, there was only one
use of _filter that could be easily replaced, since our other uses depend on
lodash's ability to handle empty variables, and the ability to filter both
objects and arrays (JS's native filter is only for arrays). Switching to native
filter in those cases would have required us to manually check the value of the
variable, set it to an empty array and/or convert it from an object to an array.

I noticed that #2131 was able to merge even though it contained a missing ;
which should have failed lint checks. I think the problem is that if fix is
enabled, running bin/web build fixes the issue and then the lint checks pass on
the fixed but uncommitted code.
We should avoid autofixing in environments that aren't development to avoid
merging unfixed code to master.

The recent routes API changes caused the Top Routes tab to stop working, as it
wasn't looking for the changed structure of the response. This PR updates that
page to accept the new API response.
This PR also adds to fields to the Top Routes query form, so that the equivalent
of linkerd routes deploy --to deploy/authors will work in the dashboard.
As mentioned in #2006, the resource detail page currently only shows inbound/outbound traffic from resources that match the type being viewed (e.g. if we are on the page for deploy/voting, inbound/outbound traffic to a daemonset won't be shown).
This branch updates the ResourceDetail code to display traffic from more than one resource type (this applies to the Octopus Graph as well).
For things that comprise pods, e.g deployments and daemonsets, we omit showing authorities,
services and pods
This PR also updates the Metric Table to handle the display of a table of multiple different resource types.
* Simplify syntax for state variable access
* Add a warning chip if a resource isn't receiving traffic
Also add a meshed chip to the resource detail pages

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

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).
Since we've switched to using css-in-js styling with material, we have very

[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.
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.
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

Try to squish the metrics columns so that the data fits on the page without

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.

Use the same tap data we use to display the unmeshed resources in the Octopus
graph to add the unmeshed rows to the Inbound stat table.
The unmeshed rows are filtered by resource type, so if we're on a Deployments
page, only upstreams which are deployments will show in the table. (Others, such
as IPs, will still show in the octopus graph).
* Use the list of unmeshed resources to display unmeshed sources in the table
* Keep track of number of pods in unmeshed sources
When I deleted a resource, I noticed that hard refreshing the page resulted in
js errors that would break the UI (e.g. if you were on a pod page, and the pod's
deployment was deleted, the pod would no longer be found, and the page would
error). This PR better handles not-present resources so that the UI still shows
up and shows you that there aren't metrics for that resource.
Also clean up the undefined/undefined octopus node that would show up in that
case.
Previously, we would display source and destination info in the Top/Tap table
popovers in a vertical format. This PR places them in a table so that each type
of source/dest (ip, pod, pod owner) can be read left to right.
* Display the popover Source/Destination info for the tap and top tables in a
tabular format
* Added an arrow column between Src and Dst
When pods or deployments are in an "Initialization" phase we currently see a "warning" icon that represents pods going under some kind of change. This may sometimes seem alarming when initially injecting pods after installing Linkerd.
This PR adds a new icon that shows up when pods are in the "PodInitializing" phase and shows the former "warning" icon when there is an error in starting pods.

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.
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.

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.
A bunch of web UI tweaks:
- Add a small success rate chart to the metrics tables
- Improve latency formatting for seconds latencies
- Rename upstream/downstream to inbound/outbound
- Make Top table look consistent with rest of tables on page
- Fix widths of metrics column columns so that tables align
Consolidate the source and destination columns into one column,
and add a direction column (To/From) so the user knows if the

* Use Tap data on Resource Detail page to display unmeshed resources
that send traffic to the specified resource.
* Don't update neighbors on every websocket recv; this causes too much rendering.
Instead, store in internal variable and update with the api results.
This branch uses the src data from tap to discern which unmeshed resources are
sending traffic to the specified resource. We then show this resource in the
octopus graph.
Note that tap is sampled data, so it's possible for an unmeshed resource to not
show up. Also, because we won't know about the resource until it appears in the
Tap results, results could pop into the chart at any time.
_.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!
