Description

Observed on a 17.2.7 cluster and confirmed on an additional 17.2.7 cluster.

Reproduction steps:
- On a cluster that reliably will have scrubs in flight set both the noscrub and nodeep-scrub flags.
- As expected ongoing scrubs and deep-scrubs will begin to be cancelled immediately and PGs that were scrubbing will be no longer.
- Unset the nodeep-scrub flag only (leave noscrub set) - at this point I would expect deep scrubs to be allowed but shallow scrubs not to be.
- Unset the "noscrub" flag as well. At this point deep-scrubs will begin on the cluster.

Expected behavior:
"noscrub" flag prevents shallow (non-deep) scrubs from starting but does not control deep scrubs.
