    Removed Zookeeper dependency from Kafka Streams. Added two test for 
creating and deleting topics. They work in IDE but fail while build. Removing 
the new tests for now.

> In Kafka Streams we need to dynamically create or update those internal 
> topics (i.e. repartition topics) upon rebalance, inside 
> {{InternalTopicManager}} which is triggered by {{StreamPartitionAssignor}}. 
> Currently we are using {{ZkClient}} to talk to ZK directly for such actions.
> With create and delete topics request merged in by [~granthenke] as part of 
> KIP-4, we should now be able to remove the ZkClient dependency and directly 
> use these requests.
