Open Stack

Hi,
I have made a first patch - https://review.openstack.org/#/c/10234. It 
was actually simpler than I had expected. By a fluke the change also 
imported better logging for the agents. This should also move to the 
openstack-common logging.
I still need to do some additional work:
1. ensure agent tests are OK
2. update devstack to support the configurations
Thanks
Gary
