Subject: [PATCH] Run k8s-on-openstack to manage k8s control plane

The k8s-on-openstack project produces an opinionated kubernetes
that is correctly set up to be integrated with OpenStack. All of the
patches we've submitted to update it for our environment have been
landed upstream, so just consume it directly.

It's possible we might want to take a more hands-on forky approach in
the future, but for now it seems fairly stable.
