add pingInterval same as used in ref C# implementation with the same logic add pingTimeout which is used to check whether pong received. If not -- drop the peer. add pingLimit which is hardcoded to 4 in TCPPeer. It's limit for unsuccessful ping/pong calls (where pong wasn't received in pingTimeout interval)
