Description

We came across a customer cluster who uses `ceph config set osd.* ...` thinking it would apply to all OSDs.
In fact this applies to zero osds, because there is no OSD named literally `osd.*`
Config set should better filter for WHO daemons that can exist, e.g. osd.<int>, mds.<string>

# ceph config set osd.* osd_max_backfills 3
# ceph config dump
WHO        MASK  LEVEL     OPTION                                 VALUE       RO
...
# ceph config dump
WHO        MASK  LEVEL     OPTION                                 VALUE       RO
...
  osd            advanced  osd_max_backfills                      10
  osd            advanced  osd_recovery_sleep_hdd                 0.000000
    osd.*        advanced  osd_max_backfills                      3
