If there's definitely no switching or routing within the cluster
networks, this sounds good to me.  Changing a host's IP would require
changes, but I don't think we can avoid those anyway.

AFAICT MAAS itself only uses the IP addresses for two things: DNS on
deployed nodes, and picking an IP address where Curtin on the node can
reach the cluster controller, if the cluster controller may have nodes
on multiple networks. We can probably find a better solution for the latter.
