    Make compute rpcapi 'live_migration' backward compatible

    This commit[1] added compute rpcapi version 4.2 which introduced a new
    argument 'migration' when calling 'live_migration' method, but the code
    did not ensure the backward compatibility with older version compute

    When calling 'live_migration' method with 'migration' argument on older
    version(like Kilo) of nova compute node, a "TypeError: live_migration()
    got an unexpected keyword argument 'migration'" will be threw up.
