Closes#776.
This branch adds the following validation to the `linkerd stat` command:
* The `--to` and `--from` flags are now mutually exclusive
* The `--to-namespace` and `--from-namespace` commands are also mutually
exclusive.
* The `namespace` resource type conflicts with the `--namespace`,
`--to-namespace`, and `--from-namespace` flags.
Examples:
```
$ bin/go-run cli/main.go stat deploy --to deploy/foo --from deploy/bar
Error: --to and --from flags are mutually exclusive
Usage:
linkerd stat [flags] (RESOURCE)
...
```
```
$ bin/go-run cli/main.go stat deploy --to-namespace foo --from-namespace bar
Error: --to-namespace and --from-namespace flags are mutually exclusive
Usage:
linkerd stat [flags] (RESOURCE)
...
```
```
$ bin/go-run cli/main.go stat namespace foo --namespace bar
Error: --namespace flag is incompatible with namespace resource type
Usage:
linkerd stat [flags] (RESOURCE)
...
```
```
$ bin/go-run cli/main.go stat ns --to-namespace bar
Error: --to-namespace flag is incompatible with namespace resource type
Usage:
linkerd stat [flags] (RESOURCE)
...
```
```
$ bin/go-run cli/main.go stat namespace --from-namespace bar
Error: --from-namespace flag is incompatible with namespace resource type
Usage:

```
$ bin/go-run cli/main.go stat ns/foo --from-namespace bar

Fixes#1405.
According to the Kubernetes Endpoints API documentation, the `name`
field in the `EndpointPort` response object is "Optional if only one
port is defined". (see
https://v1-9.docs.kubernetes.io/docs/reference/generated/kubernetes-api/v1.9/#endpointport-v1-core)
However, when the Destination service an endpoints response for a
service with a named target port, it expects the ports in the endpoints
response to have the same name as the target port in the service.
When a user creates a `NodePort` service with an unnamed port that
targets a named container port, this behaviour results in Linkerd
failing to route to that service by hostname. Without Linkerd injected,
the hostname is still reachable.
This branch fixes this issue by changing the `endpointsToAddresses`
function in `endpoints_watcher.go` to handle the case when an endpoints
response contains only a single unnamed port.
I've manually verified that this fixes the issue described in #1405.

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
Currently, when a cluster has over 100 pods injected with the Linkerd2
proxy, Prometheus metrics are not collected correctly. This is because
Prometheus appears to be making more concurrent requests than its'
proxy's outbound router cache can handle See issue #1322 for further
details.
This branch introduces a workaround for this issue, by increasing the
outbound router cache capacity to 10000 routes for the Prometheus pod's
proxy only. The router capacity limit of 100 active routes is primarily
due to the limitation of the number of active Destination service
lookups, so increasing the capacity for the Prometheus pod specifically
is probably okay, as the scrape requests are made to IP addresses
directly and therefore will not cause service discovery lookups.
This change was originally implemented and tested in @siggy's PR #1228.
I've rebased his branch onto the current `master`, and updated the code
to reflect the project name change.

The `reader.Read` method only reads as many bytes as are currently available from reader. When reading the 4 byte message length header, if not all 4 of those bytes are available, `Read` will only read the available bytes and return. This causes alignment issues when the message body is read and there are still unread header bytes in the reader. These bytes will appear at the beginning of the message body and cause a crash when the message is unmarshalled.
Use `io.ReadFull` to ensure that we read all 4 of the message length header bytes.

This change is a simplified implementation of the Builder.Path() and
Visitor().ExpandPathsToFileVisitors() functions used by kubectl to parse files
and directories. The filepath.Walk() function is used to recursively traverse
directories. Every .yaml or .json resource file in the directory is read
into its own io.Reader. All the readers are then passed to the YAMLDecoder in the
InjectYAML() function.

* Add error listener to ws object
* bin/test-cleanup: Delete test namespaces in paralllel.
My kubectl (1.9.4) waits until the `kubectl delete` operation completes,
unlike previous versions which issue the deletion request and then
immediate return. As a result of this change, bin/test-cleanup become
much slower since each deletion was happening serially. Fix this by
issuing all the deletions in parallel with a single `kubectl delete`.

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.
