This change impelements the k8s machinery for Gerrit.
This might look somewhat complex at first, but the gist of it is:
- k8s mounts etc, git, cache, db, index as RW PVs
- k8s mounts a configmap containing gerrit.conf into an external
directory
- k8s mounts a secret containing secure.conf into an external directory
- on startup, gerrit's entrypoint will copy over {gerrit,secure}.conf
and start a small updater script that copies over gerrit.conf if
there's any change. This should, in theory, make gerrit reload its
config.
This is already running on production. You're probably looking at this
change through the instance deployed by itself :)
