Versioning the pure JSON files representing the Grafana dashboards
had some disadvantages. It was hard to review them, they were very
cluttered and a lot was duplicated.
There are some tools that deal with that. One of them is Grafonnet,
which is a superset of Jsonnet, a tool to create JSON files using a
domain specific language.
This change implements the Gerrit Process dashboard in Grafonnet.
It also extends the installer to be able to install dashboards in
the Jsonnet format.

This adds the promtail version used in the setup to a file and adds
an installation step downloading promtail, if the installation is not
run in `dryrun`-mode.

The scripts were written in bash. Using bash became quite unwieldy.
Python by nature can deal well with yaml and is thus better suited
in dealing with the yaml-based configuration files. This change
rewrites the original scripts staying as close as possible to the
original ones.
Right now, the python scripts call subprocesses a lot to work with
the tools, which were already used before. At least for yaml-
templating there may be better tools that have a python integration,
which could be used in the future.
