Open Stack

Chris Dent has a change up to devstack [1] which is going to make 
nova-api/meta-api run under uwsgi by default on master (Pike).

That depends on a grenade change [2] which is simply there so we can 
roll through upgrades from Ocata to Pike with eventlet, but new installs 
in Pike via devstack will be using uwsgi.

This is just a heads up that the change is happening and once we're 
doing it in devstack then other deployment tooling projects like TripleO 
and Kolla can investigate adding support for running nova-api under 
uwsgi too.
