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.

* Add version check to Grafana dashboard
The web dashboard checks the local Linkerd version against the latest
release, and informs the user if an update is available. Grafana was not
doing this.
Modify the Grafana dashboard to perform a version check, and prompt the
user to update if needed.
