Currently, we use request_total for the variable query to determine the names in
the grafana dropdowns. We should use a non-http-based metric instead, so that if
there is only TCP traffic, the dropdowns will still be populated.
This branch uses process_start_time_seconds instead of the http-based
request_total to query for grafana variables
The control-plane's clients, specifically the Kubernetes clients, did
not provide telemetry information.
Introduce a `prometheus.ClientWithTelemetry` wrapper to instrument
arbitrary clients. Apply this wrapper to Kubernetes clients.
