Personally, I would like we can stay at Fedora Atomic/CoreOS since
Magnum has already been benefited from the container-based readonly
operating system. But we did have the discussion about using
kubeadm+ansible, however, as you can see, it's a quite big refactoring,
I'm not sure if we can get it done with current limited resources.
