We don't really need to use setup-neutron from os-cloud-config to create the ctlplane network and subnet. As simple as they are, it's more straightforward and clear to just use neutron commands directly. This removes all depedencies on os-cloud-config from instack-undercloud so we can remove that requirement from requirements.txt (and moves us closer to deprecating that entire repo).
