The election is not a separate process anymore.
It happens during the RECOVERING phase, and there's no use of timeouts anymore.

Each master node keeps a timestamp of when it started to play the primary role,
and the node with the smallest timestamp is elected. The election stops when
the cluster is started: as long as it is operational, the primary master can't
be deposed.

An election must happen whenever the cluster is not operational anymore, to
handle the case of a network cut between a primary master and all other nodes:
then another master node (secondary) takes over and when the initial primary
master is back, it loses against the new primary master if the cluster is
already started.
