[Tarantool-patches] [PATCH v4 00/12] raft: introduce manual elections and fix a bug with re-applying rolled back transactions

[Vladislav Shpilevoy]

I pushed my fixes to this branch: sp/gh-5445-election-fixes-review
as separate commits among your commits.

It does not mean the patch is perfect for push, we still have
known issues with absence of tests, and some moments we still need
to fix such as:

- Limbo ownership should not change automatically. This is the only
  way to make it more or less stable;

- The NOP filter should work regardless of election mode. Otherwise
  we still have 5445 issue when it is off;

- There are no tests for the NOP filter not working for election off;
  for a few places in box.cc in box.ctl.promote();
  for why in the NOP filter we must use txn origin ID instead of applier
  instance ID. This might lead to data loss if we did something wrong.

My commits are marked as [tosquash].

For the problems above I will create tickets if the patch is pushed as
in the branch sp/gh-5445-election-fixes-review.
