Function call of job execution

I'm curious about how dkron ensures that the Serf leader and Raft leader are on the same node. When the Raft cluster switches leaders, dkron reconciles the Serf members, doesn't it? @vcastellm

First of all, thanks for your contribution, the diagram is correct, I'll try to make it a bit more good looking and include it in documentation.

Serf it's a clustering/gossip messaging system, it doesn't have the concept of leader, when Raft switches leaders reconcile of members happens on Serf https://github.com/distribworks/dkron/blob/master/dkron/leader.go#L183 as you mention.
