    Allow port mac_address to be modified

    With ironic servers, a NIC can fail and be replaced with one that has a
    different mac. The corresponding neutron port needs to be updated with
    the new mac address so the NIC can be guaranteed to retain the same IP
    address.

    This change enables this feature in the ml2 plugin. There may need to
    be changes to other plugins to disable or complete the implementation of
    this feature.
