The installation failed, if TLS verification was disabled and no CA
certificate was given in the configuration. This happened because the
installation script always expected the CA certificate.
The installation now only expects the certificate, if TLS verification
is enabled.

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.

So far the install-script could only create a single promtail config.
Since the monitoring setup is able to monitor multiple Gerrit servers,
this caused manual work to create a promtail config per Gerrit server.
Now ytt will create a configuration for each Gerrit host configured
in the config.yaml. Ytt is only able to do that in a single file. Thus,
csplit is used to split the files into separate files that can then
be used to configure promtail on the respective hosts. The config-
files can then be found under
$OUTPUT/promtail/promtail-$GERRIT_HOSTNAME.yaml.

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.
