[rdo-users] Add baremetal to quickstart install

I'm wondering if it's possible to add a baremetal compute node to a tripleo-quickstart setup after the system is installed (or, perhaps a way to add the baremetal to a playbook). I expect one of the big problems will be getting the controller & undercloud to communicate outside it's virtual network. I had also considered doing a completely manual install, making virtualBMC VM nodes for undercloud & controller, although the network communication still ends up being an issue.
