    Fix service version to update the DB

    When new code is installed with a newer service version, the version in
    the DB should get updated.

    The fix here is to:
    1) eliminate the special case for 'version' in save()
    2) cause version to be saved on startup

    NOTE(lyarwood): Single conflict caused by the use of Mock 1.3.0 on
    stable/mitaka and as a result the lack of assert_called_once().

    Conflicts:
            nova/tests/unit/test_service.py
