    neutron: retrieve physical network name from a multi-provider network

    Multi-provider networks are a combination of vxlan and vlan networks.
    such a network has a special "segments" field that holds a list
    of networks. Each element of this list has the same structure as the 'provider
    network attributes'.
    These attributes are:
    - provider:network_type
    - provider:physical_network
    - provider:segmentation_id

    This patch will retrieve the relevant physical network name from a
    multi-provider network
