Description

If we register custom SSTable components, Cassandra would delete them when performing scrub. We need a notification sent right before deleting, so that any parties that registered custom SSTable components would have a chance to save those data from being permanently deleted.

Right now we need it for DSE - currently scrub breaks CFS compaction which relies on custom SSTable components.
