Allow librados users to opt to receive ENOSPC or EDQUOT when they submit
an operation against a full cluster. This should only be used if the
librados app can handle those errors gracefully (librbd, for example,
cannot).
Also note that this allows savvy librados users to send delete operations;
they will get either a success or EDQUOT, depending on whether the
operation results in a net drop in space utilization.

'ceph mon_metadata' was added still during this dev cycle, so there is
no need to deprecate it first.

Use a clean name for keyvaluestore (no -dev suffix), but mark as
experimental to ensure users know what they are signing up for.

Recent versions of Python contain a change to thread shutdown that
causes ceph to hang on exit; see http://bugs.python.org/issue21963.
As it turns out, this is relatively easy to avoid by not spawning
threads on exit, as Rados.__del__() will certainly do by calling
shutdown(); I suspect, but haven't proven, that the problem is
that shutdown() tries to start() a threading.Thread() that never
makes it all the way back to signal start().
Also add a PendingReleaseNote and extra doc comments to clarify.

OSDs will now rely on 'leveldb_*' config options. We do keep however
leveldb's log enabled for OSDs by passing 'leveldb_log=""' as a default
argument to global_init() on ceph_osd.cc -- however, users will be able
to override this at their own discretion.

'leveldb_*' options are currently used both by the monitor and the osd.
However, the monitor has quite different requirements from those of the
osds.
We need to specify some default values that must squash the defaults we
have for 'leveldb_*' options, while allowing users to overriding them too.
We take this not-exactly-ideal-but-still-good-enough approach of
defining the monitor-specific defaults in the 'default arguments' to
global_init(), thus allowing the user's options to take precedence over
whatever we define.

From this point onward, users should use leveldb's options and add them
to the appropriate config sections of their configuration file.
