[KAFKA-3333] - Add RoundRobinPartitioner
https://issues.apache.org/jira/browse/KAFKA-3333
The DefaultPartitioner typically distributes using the hash of the
keybytes, and falls back to round robin if there is no key. But there is
currently no way to do Round Robin partitioning if you have keys on your
messages without writing your own partitioning implementation.
I think it'd be helpful to have an implementation of straight Round Robin
partitioning included with the library.
