Revert "NIFI-2292: Funnel all cluster node status changes through the cluster coordinator instead of having each node broadcast changes to the whole cluster. This gives us the ability to increment the updateId consistently without race conditions."
This reverts commit 35ff0975bf1193a1c787af365e15a4e0da970ed9.
