Description

PHOENIX-5645 wasn't included in the master (5.x) branch because an HBase 2.x change prevented the logic from being useful in the case of deletes, since HBase 2.x no longer allows us to show deleted cells on an SCN query before the point of deletion. Unfortunately, PHOENIX-5645 wound up requiring a lot of follow-up work in the IndexTool and IndexScrutinyTool to deal with its implications, and because of that, the 4.x and 5.x codebases around indexes have diverged a good bit.

This work item is to get them back in sync, even though the behavior in the face of deletes will be somewhat different, and so most likely some tests will have to be changed or Ignored.
