Description

purged snapshots are marked in the monitor as `purged_snap_` keys. See OSDMonitor::make_purged_snap_key().
While in the OSD the purged snaps are marked as `PSN_` keys. See SnapMapper::make_purged_snap_key().
Both keys are used to find whether a snapshot were marked as purged using:
OSDMonitor::lookup_purged_snap and SnapMapper::_lookup_purged_snap correspondingly.

In order to cover cases where the OSD is missing those keys, for some reason, #53579 is proposed.
