> Currently when streams are initialised and started with streams.start(), there is no way for the caller to know if the initialisation procedure (including starting tasks) is complete or not. Hence, the caller is forced to guess for how long to wait. It would be good to have a way to return the state of the streams to the caller.
> One option would be to follow a similar approach in Kafka Server (BrokerStates.scala).
> As part of this change, we must remove the Thread.sleep() call in the Kafka Streams integration tests and substitute it with TestUtils.waitUntilTrue().
