> Before running a cleanup compaction on an SSTable we should check the range to see if the SSTable falls into the range we want to remove. If it doesn't we can just mark the SSTable as compacted and be done with it, if it does, we can no-op.
> Will not help with STCS, but for LCS, and perhaps some others we may see a benefit here after topology changes.
