        This method is overridden by the various token version plugins.

        This function should not be called independently and is expected to be
        invoked via the do_authenticate function.

        This function will be invoked if the AcessInfo object cached by the
        plugin is not valid. Thus plugins should always fetch a new AccessInfo
        when invoked. If you are looking to just retrieve the current auth
        data then you should use get_access.

S(s-Return a valid endpoint for a service.

        If a valid token is not present then a new one will be fetched using
        the session and kwargs.

        :param session: A session object that can be used for communication.
        :type session: keystoneauth1.session.Session
        :param string service_type: The type of service to lookup the endpoint
                                    for. This plugin will return None (failure)
                                    if service_type is not provided.
        :param string interface: The exposure of the endpoint. Should be
                                 `public`, `internal`, `admin`, or `auth`.
                                 `auth` is special here to use the `auth_url`
                                 rather than a URL extracted from the service
                                 catalog. Defaults to `public`.
        :param string region_name: The region the endpoint should exist in.
                                   (optional)
        :param string service_name: The name of the service in the catalog.
