Description

Expose the output topic names from TopologyTestDriver, i.e. `outputRecordsByTopic.keySet()`.

This is useful to users of the test driver, as they can use it to determine the names of all output topics. Which can then be used to capture all output of a topology, without having to manually list all the output topics.
