> Currently, logic in {{org.apache.ignite.internal.managers.discovery.GridDiscoveryManager#topologySnapshotMessage}} has major drawback, in condition we don't check that failed node with order less than oldest server node, is actually server node. So we can see invalid message about coordinator change, even though previous node was a client.
> Reproducer:
> 1. Start server #1
> 2. Start client
> 3. Start server #1
> 4. Stop server #1 and client
> We will see in logs of server #2 something like this:
