The RBD large_write test cases was taking multiple minutes to

tests: fix potential race conditions in test_ImageWatcher
The tests were sending invalid responses back to ImageWatchers
(missing the result code), which had the potential to allow the
lock to be acquired sooner than the test was expecting since
ImageWatcher would assume the last of response code meant no
clients owned the exclusive lock and would retry as fast as
possible.

Since the post-snap create header update runs asynchrously

osd/OSDMap: include pg_temp count in summary
It is useful to know how big the pg_temp map is. Strictly speaking
this is part of the OSDMap so I'm including it here. It looks like
this:
osdmap e25: 3 osds: 3 up, 3 in; 1 remapped pgs
It might be more user-friendly to put it in a line with the pgmap
somewhere (where other pg counts are included), but it doesn't quite
fit there either. So sticking with where it lives in the data
structure!

PG: compensate for bug 10780 on older peers
Previously, there was a harmless bug where we didn't fill in the
last_epoch_started field for a peer which we are resetting the
last_backfill line for. It's no longer harmless since we use that
as the activation epoch, so if the peer is missing the MIN_SIZE
feature bit, we fill in the last_epoch_started it meant to fill in.
It was possible for ImageWatcher to attempt to re-acquire held locks
via context callbacks. This issue affected resizing/flattening when
no work was required and rescheduling a watch upon two successive
failures.

With EC pool (crush rule choose indep), when there is an OSD down, the size of the 'acting' list does not change (CRUSH_ITEM_NONE is used to replace the down OSD), in this case, 'actingset' should be used to calculate the degraded objects.
Implement check_experimental_feature_enabled so that it returns the
message instead of unconditionally displaying it via derr. It allows the
caller to display it in another context.
