    Schema enhancement to support MultiSegment Network

    Description:
    Currently, there is nothing in the schema that ensures segments
    for a network are returned in the same order they were specified
    when the network was created, or even in a deterministic order.

    Solution:
    We need to add another field named 'segment_index' in
    'ml2_network_segment' table containing a numeric position index.
    With segment_index field we can retrieve the segments in the
    order in which user created.

    This patch set also fixes ML2 invalid unit test case in
    test_create_network_multiprovider().
