[Feature] Option to remove STUN to not leak IP

[Fmstrat]

Is your feature request related to a problem? Please describe.
STUN to Google is used by default, with no configuration options to remove even if the system is installed behind a VPN. This leaks out your IP to Google.

This is present in:

https://github.com/search?q=repo%3ATheSpaghettiDetective%2Fobico-server%20stun.l.google.com&type=code

And from Moonraker:

https://github.com/search?q=repo%3ATheSpaghettiDetective%2Fmoonraker-obico%20stun.l.google.com&type=code

Describe the solution you'd like
An option to disable STUN for both Moonraker-obico and the server.

Describe alternatives you've considered
Blocking Google STUN with PiHole, but that's excessive.

Neither side will respond to a STUN request without the proper credentials, because they are talking to each other through WebSockets, which are secured by credentials.

Am I missing anything here?
