    Removed unnecessary 'service_type' decorator

    @utils.service_type was introduced with 'Initial split from
    python-novaclient' commit and used for CLI. Now both Python and
    Command-line APIs for each version work well without this decorator.

    Unused 'get_service_type' function is removed too.

    'utils.retype_method' removed as well because everything works well
    without it.
