Description
This is based on a discussion over anastas's patch. The MemstoreSnapshot uses a KeyValueScanner which actually seems redundant considering we already have a SegmentScanner. The idea is that the snapshot scanner should be a simple iterator type of scanner but it lacks the capability to do the reference counting on that segment that is now used in snapshot. With snapshot having mulitple segments in the latest impl it is better we hold on to the segment by doing ref counting.
