        This is equivalent to defining DaprPublishOutput
        in the function.json which enables function to publish topic.
        All optional fields will be given default value by function host when
        they are parsed by function host.

        :param arg_name: The name of the variable that represents DaprState
        output object in function code.

        :param topic:  The name of the topic to publish to.
