A range tombstone is a tombstone that covers a slice/range of rows.

Note that in most of the storage engine, a range tombstone is actually represented by its separated opening and closing bound, see RangeTombstoneMarker. So in practice, this is only used when full partitions are materialized in memory in a Partition object, and more precisely through the use of a RangeTombstoneList in a DeletionInfo object.
