> Currently this scenario is possible:
> - joining node sent join request and waits for TcpDiscoveryNodeAddFinishedMessage inside ServerImpl.joinTopology
> - others nodes already see this node and can send messages to it (for example try to run compute job on this node)
> - joining node can not receive message: TcpCommunicationSpi will hang inside 'onFirstMessage' on 'getSpiContext' call, so sending node will get error trying to establish connection
> Possible fix: if in onFirstMessage() spi context is not available, then TcpCommunicationSpi  should send special response which indicates that this node is not ready yet, and sender should retry after some time.
> Also need check internal code for places where message can be unnecessarily sent to node: one such place is GridCachePartitionExchangeManager.refreshPartitions - message is sent to all known nodes, but here we can filter by node order / finished exchage version.
