    Physical network not included in vif details

    SR-IOV mechanism driver in networking_powervm/plugins/ml2/drivers/
    mech_pvm_sriov.PvmSRIOVMechanismDriver does not include
    'physical network' in the custom vif details. Method
    customize_vif_details prepares a dictionary like this :
    {'redundancy': 1, 'physical_ports': [u'U78C9.001.WZS05TG-P1-C5-T1'],
    'vlan': '2200', 'port_filter': False, 'capacity': 0.02}
    It does not include physical_network.
    This is not a bug, but SR-IOV vif plug mechanism in
    nova_powervm/virt/powervm/vif.PvmVnicSriovVifDriver.plug can use
    physical_network value to calculate physical ports in migration
    scenario (future work in nova_powervm).

    Above mentioned plug mechanism currently uses get_physical_network method
    in nova/network/model.VIF class. This method expects physical_network in
    custom vif details prepared by mechanism driver.

    This patchset fixes this by adding physical_network to vif details by
    getting it from network segment.

    Unit tests added.
