traefik: Only trust network for docker < 20.10

Docker complains about the network being already marked as trusted otherwise.
Also an upgrade to docker 20.10 requires manual recreation of the networks and a removal of the docker-proxy network via `firewall-cmd --zone=trusted --remove-interface=docker-proxy`.

Traefik

This will setup a Traefik server that acts as a dynamic reverse proxy and uses docker labels to route traffic. It also takes care about enabling/renewing Let's Encrypt certificates if specified.

Note: If using the IPv6 configuration: When changing the address etc, you will need to manually take care about removing old/unused firewall rules!

Requirements

You will need to have docker and docker-compose installed or declared as dependencies with their respective roles.
