Add workaround allowing to use NFS-mounts for git repositories

Using NFS volumes as Read-Write-Many volumes for the git repositories,
did not work out of the box for two reasons:

- Kubernetes is not able to mount the volume with the group given in
  the fsGroup setting. The volume was thus owned by root:root.
- The user-/group-ID mapping did not correctly work and the IDs were
  mapped to nobody.

This is now fixed by the following changes:

- The init job running before the Gerrit replica starts now has an init
  container that will chown the mounted volume to ensure that the user
  used by Gerrit has access to the repositories.
- All containers mounting the NFS-share now get a custom idmapd.conf file
  that sets the idDomain configured in the helm chart to ensure the
  correct ID mapping.
