/// <summary>
/// PingBack is called in response to a ping for a few reasons:
/// 1. This registers the node we're pinging in the sender's list of peers
/// 2. It minimally verifies that the sender is a peer.
/// 3. We can't simply ping the sender of the ping we received, as this would create an infinite loop of ping - reping.
/// NOTE: THIS IS NOT IN THE KADEMLIA SPEC EXCEPT FOR DISCUSSION OF "piggyback" PING RESPONSE.
