> After leader election happens, the followers will connect to the leader which
> is facilitated by the Learner.connectToLeader() method.
> Learner.connectToLeader() is relying on the initLimit configuration value to
> time-out in case the network connection is unreliable. This config may have a
> high value that could leave the ensemble retrying and waiting in the state of
> not having quorum for too long. The follower will retry up to 5 times.
> This patch introduces a new configuration directive that will allow Zookeeper
> to use different time-out value `connectToLeaderLimit` which then could be
> set to lower value than `initLimit`.
