OpenStackClient has a significant amount of startup overhead, which adds a non-trivial amount of time to each devstack run because it makes a lot of OSC calls. This change uses the OSC service from [0] to run a persistent process that handles openstack calls. This removes most of the startup overhead and in my local testing removes about three minutes per devstack run. Currently this is implemented as an opt-in feature. There are likely a lot of edge cases in projects that use a devstack plugin so turning it on universally is going to require boiling the ocean. I think getting this in and enabled for some of the major projects should give us a lot of the benefit without the enormous effort of making it 100% compatible across all of OpenStack.
