All Grafana graphs use shared tooltips (display all series in the
tooltip rather than the one currently moused-over), except for 3 graphs
in the Linkerd Health dashboard.
This change ensures all tooltips are shared.

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.

linkerd/linkerd2-proxy#116 removes the `classification` label for the
`tcp_close_total` metric because TCP sockets that close with an error
do not actually indicate any sort of failure -- many graceful shutdown
situations can still cause a socket error.
This change uses the `errno` label to enumerate tcp_close_total metrics.

* 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.

PR #1128 introduced new proxy process stats.
Introduce Grafana graphs that expose these new proxy process stats.

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.

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.

This PR adds the TCP metrics added in #785 and #790 to the Grafana deployment dashboards. I've added three new charts in the "Inbound Traffic" and "Outbound Traffic" headings:
+ "TCP Connection Failures": plots the number of failed TCP connections over time
+ "TCP Connections Open": shows the number of accepted and opened connections currently open
+ "TCP Connection Duration": a heatmap of connection durations over time
I'm planning on adding similar graphs to other dashboards as well in subsequent PRs.
The top-line, deployments, and health Grafana dashboards had
inconsistent layouts and data.
This change standardizes our Grafana dashboards. Every row is composed
of Success Rate, Request Rate, and Latency.

Using a vanilla Grafana Docker image as part of `conduit install`
avoided maintaining a conduit-specific Grafana Docker image, but made
packaging dashboard json files cumbersome.
Roll our own Grafana Docker image, that includes conduit-specific
dashboard json files. This significantly decreases the `conduit install`
output size, and enables dashboard integration in the docker-compose
environment.
