[APEXCORE-332][WIP] Improve partitioning to support partitioning other than
powers of 2
* Updated the Partitioner to store partition definitions as Sets of Ranges
which define which values may be accepted by what ports
* This substantially simplifies both the creation of new partitioning
schemes (e.g. evenly distributing values) and the logic around assigning values
to partitions (no confusing mask, simply a Range.contains() check)
This is still a work in progress but given that it's touching a fairly
intimate piece of the core code it would be great to get some other eyes on
this.

Updated PartitionKeys to eliminate the use of mask. This class now defines
a Set of Range values which break up the range of possible values for a
partitioning scheme. Some of the updates to the reset of the dependent code
have been made but this is still a work in progress.
