mon/MonitorDBStore: remember kv backend type If it is specified, use it; otherwise, go by the config option. Record the type when creating the store. Signed-off-by: Sage Weil <sage@redhat.com>

11.0.0
------
* If you have manually specified the monitor user rocksdb via the
``mon keyvaluedb = rocksdb`` option, you will need to manually add a file
to the mon data directory to preserve this option::
echo rocksdb > /var/lib/ceph/mon/ceph-`hostname`/kv_backend
New monitors will now use rocksdb by default, but if that file is
not present, existing monitors will use leveldb. The ``mon keyvaluedb`` option
now only affects the backend chosen when a monitor is created.
osd: change osd_crush_initial_weight = 0 to mean weight to 0 Negative now means auto-weight, 0 means weight to 0. Change the default accordingly. Signed-off-by: Sage Weil <sage@redhat.com>

* The 'osd crush initial weight' option allows you to specify a CRUSH
weight for a newly added OSD. Previously a value of 0 (the default)
meant that we should use the size of the OSD's store to weight the
new OSD. Now, a value of 0 means it should have a weight of 0, and
a negative value (the new default) means we should automatically
weight the OSD based on its size. If your configuration file
explicitly specifies a value of 0 for this option you will need to
change it to a negative value (e.g., -1) to preserve the current
behavior.
ceph-crush-location: osd_crush_location -> crush_location This was indirectly broken for OSDs as of 573c349245b7192d599a8edb15e2dade3e7170c3. Signed-off-by: Sage Weil <sage@redhat.com>

* The `osd crush location` config option is no longer supported. Please
update your ceph.conf to use the `crush location` option instead.
