The droppable tombstone ratio continues to be very high, and thus far, strategies for user-defined compactions have failed to move the needle much. Major compactions, while not a viable long-term strategy for this problem, do however result in a significant reduction to the droppable ratio, as well as reclaiming significant disk space (and it is something we can begin doing //now//).

NOTE: These compactions will all be split output (`nodetool compact -s`), resulting in 4 SSTable files (one each of 50% and 25%, and two each of 12.5%)
NOTE: In an effort to limit compaction throughput, only one compaction will be run on a host at a time
