 * <li>Wait for some time, in order for reconnection thread to increase delay between connection attempts,
 * because of reconnection failures.</li>
 * <li>Start, previously stopped nodes, and send simple query immediately. Eager reconnection is expected.
 * <b>NOTE</b>:There's still a chance that connection would be recreated by background thread and not eager
