[Openstack-operators] [Neutron] Floating IPs / Router Gateways

Probably not in the way you want.

You can have two subnets on the external network. Then you would set the
allocation pool to be nothing for the subnet that you want the router
interfaces to be attached to to make sure floating IPs aren't allocated
from it. Then whenever you attach a router interface you would need to
explicitly set the IP address to something from the first subnet.

This obviously won't work well if you want it to automatically happen for
tenants, but it might work if you are setting up the infrastructure
