* Add TCP stats to the Linkerd Pod Grafana dashboard (#2329)
* Minimize tcp stats and link it to dashboard tcp tables
* Add rows to fix minimization issues

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.

Remove the filling and stacking in request rate graphs that combine resources,
to make it easier to spot outliers.
* Grafana: remove fill and stack from individual resource breakouts
* Remove all the stacks and fills from request rates everywhere
The Grafana dashboards currently show Request Volume by ns/deploy/pod.
Add a `meshed` dimension to the Request Volume graphs, in anticipation
of the `meshed`/`secured` label from the proxy. Also increase `irate`
time window queries from `20s` to `30s`, per recommendation from
Prometheus team.
Relates to #388.

The Grafana dashboards were explicitly filtering out Conduit
control-plane data.
Remove control-plane filtering from Grafana dashboards. This brings
Grafana in-line with web, and also encourages better dog-fooding of our
proxy metrics and dashboards. Also update Grafana to 5.1.3, update the
BUILD.md architecture diagram to include Promethues and Grafana, and
introduce a Prometheus Benchmark dashboard, courtesy of Robust
Perception.

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.

Conduit 0.4.1 contained some rough edges in the Grafana deployment.
This PR include the following:
- bump Grafana to 5.1.0
- fix deployment and rc graphs when no data present
- fix some text sections overlapping due to scrolling

The top-line single stat numbers were not calculated properly, resulting
in inflated counts.
Modify the underlying Prometheus queries to ensure accurate counts of
Deployments, Pods, and Namespaces.
