Description:
 async def connect(self, *args, **kwargs):
 """Connect to a Juju controller. This supports two calling conventions: The controller and (optionally) authentication information can be taken from the data files created by the Juju CLI. This convention will be used if a ``controller_name`` is specified, or if the ``endpoint`` is not. Otherwise, both the ``endpoint`` and authentication information (``username`` and ``password``, or ``bakery_client`` and/or ``macaroons``) are required. If a single positional argument is given, it will be assumed to be the ``controller_name``. Otherwise, the first positional argument, if any, must be the ``endpoint``. Available parameters are: :param str controller_name: Name of controller registered with the Juju CLI. :param str endpoint: The hostname:port of the controller to connect to. :param str username: The username for controller-local users (or None to use macaroon-based login.) :param str password: The password for controller-local users. :param str cacert: The CA certificate of the controller (PEM formatted). :param httpbakery.Client bakery_client: The macaroon bakery client to to use when performing macaroon-based login. Macaroon tokens acquired when logging will be saved to bakery_client.cookies. If this is None, a default bakery_client will be used. :param list macaroons: List of macaroons to load into the ``bakery_client``. :param asyncio.BaseEventLoop loop: The event loop to use for async operations. :param int max_frame_size: The maximum websocket frame size to allow.
