Add init method

[Joe Gasewicz]

To make PyTaskIO class DI compatible add the following:

    def init(self, **kwargs):
        """
        :param kwargs:
        :return:
        """
        self.store_host = kwargs.get("store_host") or self.store_host
        self.store_port = kwargs.get("store_port") or self.store_port
        self.store_db = kwargs.get("store_db") or self.store_db
        self.workers = kwargs.get("workers") or self.workers
