      Description

      The transaction manager does currently not handle producer fenced errors returned from a offset commit request.

      We found this bug because we encountered the following exception in our soak cluster:

      org.apache.kafka.streams.errors.StreamsException: Error encountered trying to commit a transaction [stream-thread [i-037c09b3c48522d8d-StreamThread-3] task [0_0]]
