Matija Santl a7ee70e365 Add KVStore::CompactRange to free disk space in HA 
Summary:
Manually call `CompactRange` on KVStore (rocksDB) to free disk space
upon Raft log compaction.

Raft log takes surprisingly large amount of disk space (1MB for 1000 entries) so
we need to free disk space as we compact the log into snapshot.

When `log_size_snapshot_threshold` set to `5000` the disk usage of the
`durability_dir` goes from `4.8 MB` to `240 KB`.
