    Fix update of network's segmentation id

    In patch [1] there was added usage of context parameter in method
    get_vif_type in openvswitch mech_driver.
    This exposed that previously "wrong" context was passed to this method
    in _update_segmentation_id() method in ml2 plugin and that caused
    raising AttributeError as "Context" object didn't have attribute
    'current'.

    This patch adds new method "get_supported_vif_type" to mechanism
    drivers and this method don't need context to return what vif_types
    are supported regarding agent type.
