> Add method that checks if streams are initialised

>             Project: Kafka
>          Issue Type: Improvement
>          Components: streams
>    Affects Versions: 0.10.1.0
>            Reporter: Eno Thereska
>            Assignee: Eno Thereska
>              Labels: newbie
>             Fix For: 0.10.2.0
>
>
> 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).
> Would be good for example, to keep track of whether Kafka Streams is 
> starting/running/rebalancing
