Thanks Adrian, I think that we are on same page for this: Using nova ironic
drive to provision hyper machines as bay. ;-)  In my previous email, I also
mentioned two integration proposals with assumption of using ironic driver
provision those hyper machines.

1) Once Hyper and k8s integration finished, we can deploy k8s in two mode:
docker and hyper mode, the end user can select which mode they want to use.
For such case, we do not need to create a new bay but may need some
enhancement for current k8s bay

2) After mesos and hyper integration,  we can treat mesos and hyper as a
new bay to magnum. Just like what we are doing now for mesos+marathon.
