Create a memcached client.

        Args:
            servers (str or list of str): Server URI(s), eg '127.0.0.1:11211'.
            debug (bool): If True, quasi human readable keys are used. This helps
                debugging - run 'memcached -vv' in the foreground to see the keys
                being get/set/stored.
