feat: handle alternative query for some games

[CosminPerRam]

What is this feature about?
Although we added support for Vintage Support in #606, it has been done via using the master server method, and there is a mod for it to expose a query endpoint.

This goes the same for:

• Red Orchestra: on Unreal 2, also has Valve
• Killing Floor: on Unreal 2, also has Valve and GameSpy 1
• Unreal Tournament 2004: on Unreal 2, also has GameSpy
• Soldier of Fortune: on GameSpy 1, also has Quake 2

Additional context/references
It wouldn't hurt to provide more query methods, as (for Vintage Story) master servers will eventually be shutdown. The specified mod exposes a HTTP server and provides a GET endpoint which returns a json with the data, it seems pretty straight forward to add.

Original issue request for Vintage Story: #328
Partially replaces: #619 (side note)

Note: this PR has changed context from adding alternative query support for Vintage Support to be more general about more games that benefit from this.
