KAFKA-2273: Sticky partition assignment strategy
This PR implements a new partition assignment strategy called "sticky", and

assignments as much as possible.

> Add a new partitions.assignment.strategy to the server-defined list that will
> do reassignments based on moving as few partitions as possible. This should
> be a quite common reassignment strategy especially for the cases where the
> consumer has to maintain state, either in memory, or on disk.
