> SCM currently hands out nodes in a static order which has no information about the leader of the ring. SCM should learn about the leader in either of the following 2 ways.
> a) Ratis should add a callback to statemachine, which inturn notifies SCM of the state change.
> b) SCM periodically updates this information from the heartbeat.
