> If {{IgntieCompute.apply()}} is called on a client after reconnect, it fails. Reproducer
code is attached. The problem is that {{RoundRobinLoadBalancingSpi}} (which is default one)
is not notified about topology reset.
> Sample stack trace:
> {code}
> class org.apache.ignite.IgniteException: Task topology does not have alive nodes: [TcpDiscoveryNode
