Open Stack

Hi Steven,

Code from openstack/common/ dir is 'synced' from oslo-incubator. The
'sync' is effectively a copy of oslo-incubator subtree into a project
source tree. As syncs are not done at the same time, the code of
synced modules may indeed by different for each project depending on
which commit of oslo-incubator was synced.

Thanks,
Roman
