Open Stack

It's been a long road but due to the hard work of bauzas and melwitt the 
cells Tempest check job should now be green for changes that don't break 
cells.  The job has been red for a long time so it's likely that people 
don't think about it much.  I would ask that until we can get the 
confidence to make it voting please take notice when it's red and 
investigate or bring it to the attention of one of us in #openstack-nova.
