--------------------------------------------

Updated titles and reopened 7272 - this ticket is about improving the single-sstable tombstone compactions while 7019 is adding major compaction to LCS

> When there are no other compactions to do, we trigger a single-sstable compaction if there is more than X% droppable tombstones in the sstable.
> In this ticket we should try to include overlapping sstables in those compactions to be able to actually drop the tombstones. Might only be doable with LCS (with STCS we would probably end up including all sstables)
