This version of the patchset passes the existing tests, since Raft is disabled by default. New tests were not added yet. Changes in v2: - Fixed a bug when bootstrap couldn't finish if the first leader restarted before quorum of replicas finished bootstrap too; - Added box.info.raft; - A lot of new comments, fixed typos, and squashes between the commits.
