This updates the Grafana chart to the new repository, since the old
repository is now deprecated. This also updates the container images
and Grafana version.

This adds the promtail chart to the installation that allows to
collect the logs of the applications in the cluster, which are written
to stdout of the containers.
This will only collect logs from pods in the same namespace as the
monitoring setup. In a later change also logs from Gerrit instances
in Kubernetes will be added.

* changes:
Relabel the instance label for prometheus and loki metrics
Add dashboard for Loki metrics
Add dashboard to monitor Prometheus data
Only show Gerrit instances in the instance dropdowns
Create a configmap per dashboard
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.

The default maximum log lines shown in Grafana are 1000. This is
barely covering a few minutes in the httpd-logs.
The value of 10,000 can still be handled by the browser. More log
entries will cause the browser to cache as long as Grafana does not
provide pagination, which is planned for the future.

The most interesting new features are:
- proper limits for queried logs
- query history for logs (still a beta feature)

This change adds the current status of a project that aims to create
a simple monitoring setup to monitor Gerrit servers, which was developed
internally at SAP.
The project provides an opinionated and basic configuration for helm
charts that can be used to install Loki, Prometheus and Grafana on a
Kubernetes cluster. Scripts to easily apply the configuration and
install the whole setup are provided as well.
