Now, instead of iterating through the directories, we iterate though
directories of on of the table disks (which doesn't give us a
substantial boost but is a bit neater to read).
- Updated the system.replication_queue command types.
- Fixed the part ptr being empty (added the checksum loading and
initialization).
- Removed extra logging.
- Updated the docs to make everything clear.
- Multiple small logger fixes.
- Changed the attach_part command -- now it's after check for the
covering parts -- motivation is to do less work with the checksums
fetching.
- Better logging in the integration test.
