Feature request: Connect LAN devices via wireguard

[MGThePro]

What's the feature 🧐

Personally I find the HTTP and Shadowsocks proxy kind of inconvenient, I'd much rather have a wireguard tunnel that then sends my traffic through gluetun's VPN

I'm not sure if this should be a feature included in gluetun, or in the form of a special configuration using a seperate wireguard container running inside of gluetun's network, but I've already tried the latter and could only get the peer to connect to the wireguard server. After that it wouldn't route any internet traffic.
