Forget restic repo which do not exist
Issue in forget-backup-volumes-cephfs when it tries to forget in restic repos that don't exist (e.g. maybe the original PVC was deleted before any backup ran). It's causing errors, but the job should just do nothing (no error) if there is no restic repo for a PV.
We could add in forget_backuop_pvs.yaml
the following:
# remove any stale lock (e.g. failed backups)
if ! restic unlock; then
echo "ERROR trying to unlock PV ${PV_NAME}, probably PV was already deleted"
continue
