This now uses the new docker compose plugin.
Because we used docker-compose v1.24.1 to this point due to centos needing to install C toolchains to build never versions, the newest Docker v25 breaks compatibility and we need to use something newer.
This patch will change the name of the config file from `traefik` to
`traefik.conf`, since tor now includes `/etc/torrc.d/*.conf` in their
config file. This should make sure that the config is actually loaded.
This patch originates from the observation that new setups no longer
create the tor hidden service for traefik. Some investigation resulted
in the insight, that the tor node is no longer including the
configuration file.
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`.
With some of the recently introduced changes especially around the
defaults and ipv6 addresses, this patch fixes all remaining issues and
makes sure the docker and firewall configuration fits the expectations.
