The only way folks tend to run multinode devstack is Controller +
Compute nodes. And that sequence of creating an all in one controller,
plus additional compute nodes later, works.

Also, when running multi host (at least for nova network) we're
explicitly specifying host level direct networking, so there wouldn't be
a network node.
