> Compaction improvements: DefaultCompactor should not compact TTL-expired files

> DefaultCompactor does not check if store file can be completely purged
> because of TTL expiration. That is simple optimization which allows to
> implement such "exotic"compaction policy as FIFO compaction
> (https://github.com/facebook/rocksdb/wiki/FIFO-compaction-style).
