When a node is disconnected from the cluster, the node itself should appear as disconnected and the cluster should have a bulletin indicating the disconnect request was received. The cluster should also show n-1/n nodes available in the cluster. For example, if 1 node is disconnected from a 3-node cluster, then "2 of 3" nodes should show on the remaining nodes in the cluster. Changes to the flow should not be allowed on the cluster with a disconnected node.
