oslo.log was added to global requirements, so we can migrate to this module. Also we need this migration to be ensure that it works correctly with log-improvements. Since openstack.common.log is not dropped in oslo-incubator, we shouldn't remove it. Change-Id: I90468e4db812ae0b5d8a43a37206b236f8904661 Closes-bug: #1412673
