We are now relying on host routes feature of neutron-dhcp-agent,
so it's time to disable nova bm file injection in undercloud
and use neutron-dhcp-agent instead (if file injection is enabled
the static route for metadata server is not set and overcloud
machines hit seed vm metadata server instead of undercloud one).
