-------------------------------------

Hey Guozhang, this looks like a reasonable approach. But we should probably do 
some code de-dup on this, let's talk tomorrow in person.
                
> Avoid a full rebalance in cases when a new topic is discovered but 
> container/broker set stay the same

> Currently a full rebalance will be triggered on high level consumers even 
> when just a new topic is added to ZK. Better avoid this behavior but only 
> rebalance on this newly added topic.
