    Add new configuration group ``ovs_driver`` and new configuration option
    under it ``vnic_type_prohibit_list``, to make the previously hardcoded
    ``supported_vnic_types`` parameter of the OpenvswitchMechanismDriver
    configurable.
    The ``vnic_types`` listed in the prohibit list will be removed from the
    supported_vnic_types list.
