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 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`.

The public-api previously only permitted 4 hard-coded time windows:
10s, 1m, 10m, 1h. This was primarily a relic of the recently removed
telemetry system.
Modify the public-api to validate the time string, but allow for any
window size, which is then passed through to Prometheus.

* 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 new statsummary command accepted friendly k8s names, which worked
for k8s queries, but Prometheus requires a specific key.
Modify the statsummary query to map friendly k8s names to canonical k8s
names when constructing the query. Then during the query, map the
canonical k8s name to a specific Prometheus label.

Follow-up from #315.
Now that the UIs don't report per-path metrics, we can remove the path label from Prometheus, the path aggregation and filtering options from the telemetry API, and the path field from the proxy report API.
I've modified the tests to no longer expect the removed fields, and manually verified that Conduit still works after making these changes.
