[Tarantool-patches] [PATCH 0/6] Instance join should prefer booted instances

[Vladislav Shpilevoy via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

See the commit messages for the details.

I did some basic tests for backward compatibility since I added a new field to
the ballot, and it works fine.

Branch: http://github.com/tarantool/tarantool/tree/gerold103/gh-5613-boot-scores
Issue: https://github.com/tarantool/tarantool/issues/5613

Vladislav Shpilevoy (6):
  replication: refactor replicaset_leader()
  replication: ballot.is_ro -> is_ro_cfg
  replication: ballot.is_loading -> is_ro
  replication: introduce ballot.is_booted
  replication: use 'score' to find a join-master
  replication: prefer to join from booted replicas
