This makes use of the code generated client added in #1752

Sometimes, the tap server causes the controller pod to restart after it receives this error.
This error arises when the Tap server does not close gRPC tap streams to proxies before the tap server terminates its streams to its upstream clients and causes the controller pod to restart.
This PR uses the request context from the initial TapByReource to help shutdown tap streams to the data plane proxies gracefully.

Previously, we would tap any resource's pods, regardless of whether the pods
were meshed or not. We can't actually tap non-meshed pods, so I'm adding a check
that will filter out non-meshed pods from the pods that tap watches.
Previous behaviour:
When attempting to hang a non meshed pod, it would establish
a watch on the pods, but then never return any results. In the CLI you could
just cancel it with Ctrl-C. In the web, clicking Stop would send a
WebSocket.close(1000) but wouldn't actually close the connection...
Behaviour after change :
If no pods under the specified resource are meshed, it'll
return an error of no pods being found to tap
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.
* Add controller admin servers and readiness probes
* Tweak readiness probes to be more sane
* Refactor based on review feedback

The `conduit tap` command is now deprecated.
Replace `conduit tap` with `connduit tapByResource`. Rename tapByResource
to tap. The underlying protobuf for tap remains, the tap gRPC endpoint now
returns Unimplemented.
Fixes#804

public-api and and tap were both using their own implementations of
the Kubernetes Informer/Lister APIs.
This change factors out all Informer/Lister usage into the Lister
module. This also introduces a new `Lister.GetObjects` method.

The TapByResource endpoint was previously a stub.
Implement end-to-end tapByResource functionality, with support for
specifying any kubernetes resource(s) as target and destination.
