I guesstimate that around 50% of the operator log volume when set to log
level `DEBUG` are messages about cm's which aren't relevant to rook.
E.g.:
```
2022-09-16 23:03:05.430839 D | ceph-cluster-controller: hot-plug cm watcher: only reconcile on hot plug cm changes, this "ingress-controller-leader" cm is handled by another watcher
2022-09-16 23:03:05.643255 D | ceph-cluster-controller: hot-plug cm watcher: only reconcile on hot plug cm changes, this "fleet-agent-lock" cm is handled by another watcher
2022-09-16 23:03:05.799526 D | ceph-cluster-controller: hot-plug cm watcher: only reconcile on hot plug cm changes, this "cattle-controllers" cm is handled by another watcher
```
Yes, it is `DEBUG` and noise is expected. However, there is no message
about checking the status of the cm's rook actually needs to watch and
these messages don't seem very useful. I have been resorting to piping
the operators logs through `| grep -v 'hot-plug cm watcher'` to cut down
the noise.
