Game server network tester

## User Story

As a server admin, I want network tools to better help configure game server networking

## Basic info

* Command: New command

## Further Information

Configuring network settings for game servers can be quite confusing if you are new to networking. This is extra confusing if the game server is behind a firewall of home router. A new command is to be created that will diagnose and provide information about the current configuration of networking for the game server

including:
* query tests (internal and external)
* open port tests (internal and external)
* LAN detection
* Optional UPNP support for LAN servers upnpc command.
* optional external query
* Ping different locations to test ms response times.
* display IP info

some features may require an external service of some sort which may be problematic.
