Project: Ignite
Issue Type: Bug

In some cases after the coordinator change, the client node can be failed
before it can establish a connection to another server from the cluster.

It looks like a race condition.
Steps to reproduce:
1. Start server A.
2. Start client.
3. Start server B.
4. Stop server A.
If add Thread.sleep(10000) between (3) and (4) then the client node won't be
disconnected from the cluster.
Reproducer is attached [^ClientDisconnectedTest.java].
