Description

The KStreamTestDriver and related fixtures defined in streams/src/test/java/org/apache/kafka/test would be useful to developers building applications on top of Kafka Streams, but they are not currently exposed in a package.

I propose moving this directory to live under streams/fixtures/src/main and creating a new 'streams:fixtures' project in the gradle configuration to publish these as a separate package.
