This patch adds PDBs for all main deployments with a hardcoded
maxUnavailable 1. This should help to make sure that updates go smooth
and without major downtimes, as soon as at least 2 replicas are running,
while still not blocking cluster updates.

Furhter it makes the redis dependency optional, helping to replace the
integrated redis with a separate or external redis service.

This patch should make redis HA, which should eliminate another SPOF for
goharbor. This is the first usage for the new redis operator.

This patch provides some basic operator configs to get resource requests
and limits in place along with enabling the built-in operator monitoring

Currently 3.3.0 has a bug, where the CRDs contain templating that
doesn't work, resulting in failed installations.

This patch removes the `rollme` annotation that is used to force
redeployments on upgrades. However, it's quite unnecessary since config
changes and image upgrades are already covered.

Currently it causes more harm than helping.
