Are these prefixes totally private to Neutron/DVR? I.e. we're not
going to trip over ourselves by assuming that if "fip" and "snat"
are there that we're looking at a DVR configuration?

It doesn't really affect the current patch but it would be useful
information to help inform future changes (e.g. right now the
Neutron plugin runs unconditionally - even on hosts with none of
the OpenStack components installed).
