> Currently there is only a beforeReleasePartition callback in consumer
> rebalance listener of ZookeeperConsumerConnector. It is useful to have an
> afterRebalance callback with new partition assignment passed in. There are
> some use cases where knowing the topic partition changes is useful (e.g.
> mirror maker can create same number of partitions for new topic in target
> cluster). The new consumer will have such callback but probably won't be
> production ready very soon. Because adding this callback is not much amount
> of work so we can do this as a short term solution.
