Serge Petrenko (7):

  replication: forbid implicit limbo owner transition
  txn_limbo: fix promote term filtering
  txn_limbo: persist the latest effective promote in snapshot
  replication: send latest effective promote in initial join
  box: introduce `box.ctl.demote`
  box: make promote/demote always bump the term
