Persist the Gerrit site in a single volume

So far most of the Gerrit site was stored in an EmptyDir-Volume and only
some parts were each persisted in a dedicated persistent volume. While
providing flexibility this approach would lead to a huge amount of
persistent volumes and could easily cause inconsistencies.

Now the whole Gerrit site except for the repositories are stored in
a single persistent volume. The default volume size is set to 10 Gb, but
can be configured in the helm-charts. This was changed for the gerrit-
master and the gerrit-slave chart.

The gerrit-init script will now check whether a gerrit.war is already
installed in the site, whether it has the same version as in the
container and whether new plugins should be installed or others
uninstalled and will initialize, if one of these conditions is not met.
