librbd: fix race between unprotect and clone
Clone needs to actually re-read the header to make sure the image is
still protected before returning. Additionally, it needs to consider
the image protected *only* if the protection status is protected -
unprotecting does not count. I thought I'd already fixed this, but
can't find the commit.

librbd: add {rbd_}open_read_only()
Since 58890cfad5f7bee933baa599a68e6c65993379d4, regular {rbd_}open()
would fail with -EPERM if the user did not have write access to the
pool, since a watch on the header was requested.
For many uses of read-only access, establishing a watch is not
necessary, since changes to the header do not matter. For example,
getting metadata about an image via 'rbd info' does not care if a new
snapshot is created while it is in progress.

osd: allow RecoveryDone self-transition in RepNotRecovering
In a mixed cluster where some OSDs support the recovery reservations and
some don't, the replica may be new code in RepNotRecoverying and will
complete a backfill. In that case, we want to just stayin
RepNotRecovering.
It may also be possible to make it infer what the primary is doing even
thought it is not sending recovery reservation messages, but this is much
more complicated and doesn't accomplish much.

osd: drop 'osd recovery max active' back to previous default (5)
Having this too large means that queues get too deep on the OSDs during
backfill and latency is very high. In my tests, it also meant we generated
a lot of slow recovery messages just from the recovery ops themselves (no
client io).
Keeping this at the old default means we are no worse in this respect than

osd: fix pg stat msgs vs timeout
We can get a pattern like so:
- new mon session
- after say 120 seconds, we decide to send a stats msg
- outstanding_pg_stats is finally true, we immediately time out (30 second
grace), and reconnect to a new mon
-> repeat
The problem is that we don't reset the last_sent timestamp when we send.
Or that we do this check after sending instead of before. Fix both.
This should resolve the issue #3661 where osds that don't have pgs
updating are not stats messags to the mon to check in, and are eventually
getting marked down as a result.
