David Zafman fa698e18e1 mon: Improve health status for backfill_toofull and recovery_toofull
Treat backfull_toofull as a warning condition because it can resolve itself.
Includes test case for PG_BACKFILL_FULL
Includes test case for recovery_toofull / PG_RECOVERY_FULL

Fixes: https://tracker.ceph.com/issues/39555
