Remove

When the remove command is executed the node should show as disconnected from a cluster. The nodes remaining in the cluster should show n-1/n-1 nodes. For example, if 1 node is removed from a 3-node cluster, then the remaining 2 nodes should show "2 of 2" nodes. The cluster should allow a flow to be adjusted. The removed node can rejoin the cluster if restarted and the flow for the cluster has not changed. If the flow was changed, the flow template of the removed node should be deleted before restarting the node to allow it to obtain the cluster flow (otherwise an uninheritable flow file exception may occur).
