Ping Packet should contain information about host

The ping packet doesn't contain the host server is connecting to. This isn't useful for operators that administrate proxy servers like BungeeCord. If there would be an information about the host, the proxy knows the right server to answer or to forward. I know that this bug is partial a duplicate of MC-137, but this time, more and more people are administrating their own server networks with BungeeCord. And in this case, it would be very useful to add this packet field. Otherwise it would make no sense because Handshake packet already contains such a field.
