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.

yaml manifest output.
Update web UI with daemonsets
Update navigation, overview and pages to list daemonsets and the pods
associated to them.
Add daemonset paths to server, and ui apps.

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.

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.

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 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.

Conduit's Grafana currencly provides Top-line, Deployment, Pod, and Mesh
Health dashboards.
This change adds a new Conduit Service dashboard. In addition to
top-line information, this dashboards focuses primarily on requests to a
Service, as only dst_service is available in our metrics.

The Grafana dashboards key off of deployment, but had no awareness of
namespaces, causing incorrect metrics aggregation and display.
This change makes the Grafana dashboards key off of namespaces, and also

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.
