* Fix bug where we were dropping parts of the StatSummaryRequest
* Add tests for prometheus query strings and for failed cases
Problem
In #928 I rewrote the stat api to handle 'all' as a resource type. To query for all resource types,
we would copy the Resource, LabelSelector and TimeWindow of the original request, and then
go through all the resource types and set Resource.Type for each resource we wanted to get.
The bug is that while we copy over some fields of the original request, we didn't copy over all
of them - namely Resource.Name and the Outbound resource. So the Stat endpoint would
ignore any --to or --from flags, and would ignore requests for a specific named resource.
Solution
Copy over all fields from the request.
I've also added tests for this case. In this process I've refactored the stat_summary_test code
to make it a bit easier to read/use.
The existing `tap` command is being deprecated.
Introduce a `tapByResource` cli command. It supports tapping a Kubernetes
resource or collection of resources, optionally filtered by outbound resources.
This command will eventually replace `tap`.

This changes the public api to have a new rpc type, `TapByResource`.
This api supersedes the Tap api. `TapByResource` is richer, more closely
reflecting the proxy's capabilities.
The proxy's Tap api is extended to select over destination labels,
corresponding with those returned by the Destination api.
Now both `Tap` and `TapByResource`'s responses may include destination
labels.
This change avoids breaking backwards compatibility by:
* introducing the new `TapByResource` rpc type, opting not to change Tap
* extending the proxy's Match type with a new, optional, `destination_label` field.
* `TapEvent` is extended with a new, optional, `destination_meta`.
* Remove the telemetry service
The telemetry service is no longer needed, now that prometheus scrapes
metrics directly from proxies, and the public-api talks directly to
prometheus. In this branch I'm removing the service itself as well as
all of the telemetry protobuf, and updating the conduit install command
to no longer install the service. I'm also removing the old version of
the stat command, which required the telemetry service, and renaming the
statsummary command to stat.
* Fix time window tests
* Remove deprecated controller scrape config

The success rate calculation relies on the `classification` label, but
was incorrectly specifying `fail` rather than `failure`.
Fix public api to specify `failure`. Also re-org public api tests for
easier Kubernetes and Prometheus mocking.

* Define a new telemetry Stat API
Proposal definition for a new Stat API, for the purposes of satisfying the queries proposed in #627.
StatSummary will replace Stat once implemented and the original Stat deleted.
