Feat: HaProxyAddress

[PinoOG]

• Exposes for the InboundConnection the SocketAddress related to the HaProxy Address which transports the player tcp connection. Mostly for debugging / diagnostic reasons.
• This can be useful to diagnose if players with high latency are sharing the same HaProxy Address.
• Given that the majority of networks run velocity behind services like TCPShield or similar, exposing the HaProxyAddress can give them some benefit for debugging.
