> CFS compaction strategy coming up in the next DSE release needs to store some important information in Tombstones.db and RemovedKeys.db files, one per sstable. However, currently Cassandra issues warnings when these files are found in the data directory. Additionally, when switched to SizeTieredCompactionStrategy, the files are left in the data directory after compaction.
> The attached patch adds new components to the Component class so Cassandra knows about those files.
