Well, data is certainly unavailable, and may also be
degraded in the sense that we can't peer. I think
unavailable is the more severe of the two, though, so
let's put it there!

No longer output MDS_* versions as well as FS_* versions,
because it was noisy and the important message is about
the availability (or not) of the filesystem.
Revise the _FAILED check to only raise the message if
there are not suitable replacements available for failed
ranks. This avoids a spurious health check failure when
a rank has been failed (e.g. by the admin) but it will
be replaced at the next tick().
After this change, doing a "ceph mds fail" when a standby
is available just gives you a single FS_DEGRADED health
check from the point of the "fail" to when the replacement
is active.

Add explicit messages, and demote the addr+state prints
to DEBUG level. At INFO level we now see
just a message when we decide to assign a rank, and
a message when the daemon is active, rather than messages
for each state the daemon progresses through.

This does several little things that add up to big concurrency and safety
improvements:
* Switch to passing around PGRefs instead of raw pointers, which is
generally a good idea
* drop the pg_map_lock once we're done looking up the PGRefs, since
we don't need it and holding the PG pointer alive was the only previous
thing that might have made it necessary
* don't hold the recovery_lock since we don't need any OSD-level
synchronization
* make sure the PG is not being deleted before we do a force-change of its
state

The summary field can be extended with the fields
used to construct the message (e.g. including
the down osd count in the message about osds
being down).
The detail entries, similarly, can be extended
with machine-readable fields like the PG ID
for a damaged PG.
For the moment all the internal stuff is just
strings still, but we change the output format
so that we don't break it later when we
add things.
