This sync is crucial to adopting oslo.log, the bulk of the changes
are for the oslo modules to use python standard logging instead of
relying on oslo.log.
from keystone:
rm -rf keystone/openstack/common
from oslo-incubator:
python update.py ../keystone
Had to undo the changes to local.py and log.py since they are still
being used throughout keystone.
Also, with the sync came a change to versionutils, which now
emits a deprecation exception from versionutils instead of
the incubator's log.py. This meant that a test had to be updated
to catch the appropriate exception.
