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.

Grafana provides default dashboards for Prometheus and Grafana health.
The community also provides Kubernetes-specific dashboards. Conduit was
not taking advantage of these.
Introduce new Grafana dashboards focused on Grafana, Kubernetes, and
Prometheus health. Tag all Conduit dashboards for easier UI navigation.
Also fix layout in Conduit Health dashboard.
