Title:
  Replication handshake

Status in Tarantool - an efficient in-memory data store:
  Confirmed

Bug description:
  If a replica connects to a wrong server port, it may hang indefinitely.
  This can lead to quite mysterious replication problems: the replica starts, 
but doesn't get any updates from the master.

  Add a replication handshake, and possibly a timeout to establish it
  (or simply don't start until it's established). If can't handshake,
  don't fall through into read-events mode.

  Or add authentication and merge all ports into one based on
  authentication data.
