ceph-disk: enable directory backed OSD at boot time
https://github.com/ceph/ceph/commit/539385b143feee3905dceaf7a8faaced42f2d3c6
introduced a regression preventing directory backed OSD from starting at
boot time.
For device backed OSD the boot sequence starts with ceph-disk@.service
and proceeds to
systemctl enable --runtime ceph-osd@.service
where the --runtime ensure ceph-osd@12 is removed when the machine
reboots so that it does not compete with the ceph-disk@/dev/sdb1 unit at
boot time.
However directory backed OSD solely rely on the ceph-osd@.service unit
to start at boot time and will therefore fail to boot.
The --runtime flag is selectively set for device backed OSD only.
mon/OSDMonitor: transit creating_pgs from pgmap when upgrading
there could be some pg(s) still being created when we are upgrading to
luminous, and the pools holding them are not changed in the sense of
pg_pool_t::last_change after the upgrade and before we scan for
creating pgs. in that case, the existing update_pending_creatings()
will fail to collect the pgs being created before the upgrade.
with this change, the creating_pgs in pgmap are also used for updating
the OSDMonitor's creating_pgs if it's updated.
but we should stopupdating the pgmap once the upgrade completes. i.e.
stop dispatching MSG_PGSTATS messages to PGMonitor if the quorum and all
osds are luminous.

mds: shut down finisher before objecter
Some of the finisher contexts would try to call into Objecter.
We mostly are protected from this by mds_lock+the stopping
flag, but at the Filer level there's no mds_lock, so in the
case of file size probing we have a problem.

We get ENOENT when a pool doesn't exist. This can

mon: emit cluster log messages on MDS health changes
Previously, when we got a beacon that updated the health

cluster log messages indicating a rising fsmap epoch number.
It would be good to do this for health messages in general at
some point, but for now just do it for the MDS ones.

Pending introduction of offset name hint, our caller will just be

If we don't set the luminous flag, we should not set the new luninous

epoch where the flag is eventually set and the encoded map finally includes
the field we have set in memory.)

tools/cephfs: set dir_layout when injecting inodes
When we left this as zero, the MDS would interpret it was HASH_LINUX
rather than the default HASH_RJENKINS. Potentially that
could cause problems if there perhaps were already dirfrags in
the metadata pool that were set up using rjenkins. Mainly
it just seems more appropriate to explicitly set this field
rather than hit the fallback behaviour.
