-creates a single PDB (max-unavailable=1) for all OSDs. This PDB allows one OSD to go down at a given time.
-When a drain is detected, blocking PDBs (max-unavailable=0) will be created for each failure domain that is not being drained and the main PDB (max-unavilable=1) will be deleted. This will allow all the OSDs in the currently drained failure domain to be removed while blocking the deletion of OSDs in other failure domains.
-Once the PGs are healthy again, the blocking PDBs will be deleted and the main PDB will be restored.
-Add PG healthcheck timeout
-Delete any legacy node drain pods and blocking OSD PDBs
