Review request for hbase, stack and khemani.
Summary
-------
Adds a new Increment class that allows multiple columns (each w/ own increment
amount) in a single row being incremented in one call.
The big wins here are being able to do multiple columns in a row in a single
RPC and having it be appended/synced to the WAL in a single call.
The current trade-off is that you lose atomicity to readers (ie. this does not
currently use RWCC). Eventually it could but for the current use case I am
building this for, it's okay like this.
This addresses bug HBASE-2946.

Testing
-------
Added TestFromClientSide.testIncrement() which adds some client-side tests of
Increment (and mixing w/ original icv call). That passes and most the way
through a test suite run.
Thanks,
Jonathan
