Remove the telemetry service (#757)

* 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
