Add temporary solution in order to support multiple physical networks by mlnx ML2 MechanismDriver. Due to non merged patches in nova that should support propagating physical_network retrieved from port binding:profile attribute to VIF/Network object. The code will be removed once relevant nova patches are merged. The code is disabled by default and should be enabled via ml2_conf_mlnx.ini config file.
