@sbueringer we spoke about having at least 180s for RemoteConnectionGracePeriod. Is this a good chance to check for this here or was this a different thing?

I'll do this as part of my PR and I'm going to enforce it directly on the flag (maybe additionally in these places, but I'll take care of that)
Goal of this PR is mostly to safeguard against cases where ClusterCache etc is nil or grace period is not set at all. So that we don't have to check e.g. ClusterCache for nil in other parts of the reconciler code
