------------------------------------------------
May be I can this up and see if it is good to go ahead with what this JIRA
intended or do as how SQM is being refactored on a case by case basis.
> Handle deletions and column tracking using internal filters rather than using
> DeleteTrackers and ColumnTrackers

> See HBASE-11054 for discussion.
> Currently the delete tracking is done by DeleteTracker and its subclasses.
> column tracking and its versions are handled inside the ColumnTrackers and
> its subclasses.
> This JIRA aims at providing internal filters and attaching them to
> scans/gets, including minor and major compaction scans so that all the logic
> of deletes and version counting goes into it rather than having trackers.
