This gets us started on adding a Traefik role and hooking Traefik:
- directly to services which support Traefik - we only have a few of
these right now, but the list will grow
- to matrix-nginx-proxy for most services that integrate with
matrix-nginx-proxy right now
Traefik usage should be disabled by default for now and nothing should
change for people just yet.
Enabling these experiments requires additional configuration like this:
```yaml
devture_traefik_ssl_email_address: '.....'
matrix_playbook_traefik_role_enabled: true
matrix_playbook_traefik_labels_enabled: true
matrix_ssl_retrieval_method: none
matrix_nginx_proxy_https_enabled: false
matrix_nginx_proxy_container_http_host_bind_port: ''
matrix_nginx_proxy_container_federation_host_bind_port: ''
matrix_nginx_proxy_trust_forwarded_proto: true
matrix_nginx_proxy_x_forwarded_for: '$proxy_add_x_forwarded_for'
matrix_coturn_enabled: false
```
What currently works is:
reverse-proxying for all nginx-proxy based services **except** for the Matrix homeserver
(both Client-Server an Federation traffic for the homeserver don't work yet)
