Algorithm
----------

Let's say we have a cluster of nodes A < B < C where A is the leader, and B and C are
candidates. We want to add a new candidate D to the cluster, and we select node B as
the seed node.
When node D is started, the following happens:

(1) D sends a 'join' msg to B, and D starts monitoring B
(2) B replies with a 'hasLeader, A' message
