> This patch fixes two issues with the OCC transactions:
> - Overly conservative read-set. Previously a scanner was claiming read set on the whole
region. This patch gets the read set from the start and end keys that a scanner was opened
with (the start key comes from the arg to open, the end key comes from a WhileMatch(StopRow())
filter if present. 
> - A potential ConcurrentModificationException.
