Rodolfo Alonso Hernandez 55afd9bc92 [OVN] Allow only one physical network per bridge
Same as in other ML2 plugins (OVS, Linux Bridge), OVN mechanism driver
should allow only one physical network per bridge. The rule "one
network, one bridge" should be present in OVN too.

By allowing only one physical network per bridge, Neutron prevents
having two networks with subnets with the same CIDR in the same bridge.
Currently is possible and this CIDR clash is not prevented (shouldn't be
by the API). This architectural limitation prevents this situation.

This limitation is already present in deployment tools as TripleO.
