    Enable logging for the *saltyrtc* logger group.

    Arguments:
        - `level`: A :mod:`logbook` logging level. Defaults to
          ``WARNING``.
        - `redirect_loggers`: A dictionary containing :mod:`logging`
          logger names as key and their respective :mod:`logging` level
          as value. Each logger will be looked up and redirected to
          :mod:`logbook`. Defaults to an empty dictionary.

    Raises :class:`ImportError` in case :mod:`logbook` is not
    installed.
