Description

Currently TcpDiscoveryMulticastIpFinder on start sends mcast address request and stops wait when at least one remote address is received.
This scenario is possible:

• 4 nodes start concurrently
• node1 receive first address of node2, node2 from node1
• node3 receive first address of node4, node4 from node3
• node1/node2 and node3/node4 can form separate clusters
