    Limit ML2 delete_network/subnet retries

    Monkey-patch ML2's delete_network() and delete_subnet() methods to
    limit the number of times they retry to avoid potential infinite
    loops. Also add some logging to help determine when/why the
    delete_network() loops occur. This does not resolve the actual bug -
    it just mitigates the damage when it occurs.
