Notification for grid node discovery events.

Parameters:

type - Node discovery event type. See DiscoveryEvent

topVer - Topology version or 0 if configured discovery SPI implementation does not support versioning.

node - Node affected (e.g. newly joined node, left node, failed node or local node).
