[Tarantool-patches] [PATCH 0/8] dRaft

[Vladislav Shpilevoy]

The patchset implements Raft. It does not have any tests, nor passes the
existing tests, but should be close to a future pushable version.

The last commit will be split into more patches, and partially squashed into the
previous commits. But it is not expected to change it significantly.
