I did not commit this because there is currently a performance investigation going on which I do not want to disrupt.

> In a time-limited setup, the producer stops producing messages after the duration expired.
> It is possible that the consumer continues to try to consume messages after this point eventually draining the queue. This means it receives less messages than it could effectively reducing its reported consumption rate.
> Producers should continue to produce messages until they are notified by the controller that all consumers are done consuming.
> This could happen in the TearDownTest command or in a new StopTest command.
