TRACE glance File "/usr/bin/glance-api", line 10, in <module>
TRACE glance sys.exit(main())
TRACE glance File "/usr/lib/python2.7/site-packages/glance/cmd/api.py", line 80, in main

    Fix OSProfiler exception when is enabled

    When OSProfiler is enabled in glance-api.conf or glance-registry.conf,
    the services are failing to start. They raise an AtttributeError
    exception when not finding messaging module from notifier

    When oslo removed namespaced packages in kilo, the code was changed
    in glance.notifier from doing

     from oslo import messaging

    To doing

            import oslo_messaging

    And all references were changed from messaging to oslo_messaging. When
    osprofiler integration was added, the author choose to use the notifier
    module's reference to oslo.messaging instead of importing it directly.
    When the rename occurred, this was not caught. So, oslo_messaging is
    directly imported in glance.cmd.{api,registry,search} and use it as
    it was intended

    Closes-Bug: #1467982
