Grafana provides a repository for dashboards that can be used to easily
import dashboards. Providing these dashboards there would make it easier
for users not using the full setup provided here to still use the
dashboards. To be able to upload however, the datasource reference in the
dashboards has to be a template.
This is however not compatible with the way how the dashboards are imported
in the Grafana of the stack provided here. Thus, the variables are
removed during the installation.

This change
- adds metrics for parallel GC to the GC panel in the Gerrit Process
dashboard
- configures the GC panel to only show queries with values other than
null
- changes the interval to one minute, which fits the scrape interval
- changes the default time frame to the last 24h, which is used for
most other dashboards

So far it was only possible to monitor single instance Gerrit servers.
This was due to to the fact that a URL had to be used that pointed to
a dedicated instance, since if multiple replicas would be behind the
instance, the metrics of a random replica would be scraped and not of
all.
Prometheus has a service discovery functionality for deployments running
in Kubernetes. This is now used, when monitoring a Gerrit instance in
Kubernetes. This allows to have a variable number of replicas running,
which will be automatically discovered by Prometheus.
The dashboards were adapted accordingly and allow now to select the
replica to be observed. For now, no summary of all replicas can be
displayed in the dashboards, but that feature is planned to be added
in the future.

A variable was used to select the Gerrit instance to observe in the
dashboards. Since the instance label is set for all targets that
prometheus scrapes, the variable would also contain e.g. the prometheus
instance.
Now only Gerrit instances are displayed by further filtering for a
metric specific for Gerrit.

I the dashboard files got too large (>2Mb) Kubernetes was rejecting
the configmap.
Now each dashboard is installed with an own configmap. A sidecar container
is used to register these dashboards with Grafana.
