…action (apache#7993) Add DeleteTracker.isRedundantDelete() to detect when a delete marker is already covered by a previously tracked delete of equal or broader scope. ScanDeleteTracker implements this for all four delete types: - DeleteFamily/DeleteFamilyVersion: covered by a tracked DeleteFamily - DeleteColumn/Delete: covered by a tracked DeleteFamily or DeleteColumn MinorCompactionScanQueryMatcher calls this check before including a delete marker, returning SEEK_NEXT_COL to skip past all remaining cells covered by the previously tracked delete. Compatible with KEEP_DELETED_CELLS. When set to TRUE, trackDelete() does not populate the delete tracker, so isRedundantDelete() always returns false and all markers are retained.
