Sometimes mount A would get a cap revoke when mount
B did its last IO, resulting in mount A's OSD epoch
getting updated too.
Fix by making sure mount B is the last one to have
done IO before we do the barrier, so that when
it does IO again after the barrier, mount A can't
be holding any caps that B would need.

The interval between writes was too short because
it was not taking account of the way OSDMap full
flags are set on tick rather than immediately.

Run the same procedure as TestClusterFull, but
instead of limiting OSD memstore size, use pool
quota on the data pool.

...to avoid having boilerplate in each test module,
and gain the ability to run them all in one go
with a nice test-by-test pass/fail report.
