py4j.Py4JException: Method createTopic([class java.lang.String]) does not

From Java clients' POV, the signature of `createTopic()` in KafkaTestUtils
has changed, so you'll need to explicitly provide the extra argument from the
Python caller or will need to add back a single-argument constructor for
backwards-compatibility.
