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](https://docs.traefik.io/v2.0/) 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.
Role Variables
--------------
**Please look at the [defaults/main.yml](defaults/main.yml) for all available variables and their description.**
**Note: Lines that are commented out via `#` are usually still valid/used variables, but they are not defined by default, so they might enable a feature, when uncommenting/defining them!**
### Global variables, that are used:
- `docker_package`: Defined by the docker role, this is the package name of docker within your package manager.
Dependencies
------------
- docker
- docker-compose
