By default, swarm services use ingress mode port publishing, which is
not ideal for traefik (it breaks IPv6 ingress and there is no need to
load-balance traffic between multiple traefik instances or to route it
from multiple swarm nodes)
This PR switches traefik's port publishing mode to `host` for all of
its exposed ports as well as:
* change traefik's update order to stop-first (there cannot be multiple
containers exposing the same port when using host-mode publishing)
* use `endpoint_mode: dnsrr` instead of the default `vip`
* remove all overrides from `compose.host.yml`, leaving the file empty
for backwards compatibility
/!\ This is a breaking change
Closes: #52
* [x] I have deployed and tested my changes
* [x] I have added a [release note entry](https://docs.coopcloud.tech/maintainers/upgrade/#creating-new-release-notes)

# Support P2P communication between P2Panda Apps
Apps built with the set of [P2Panda](https://p2panda.org/) libraries perform P2P communication over two UDP ports. The default ports for these are 2022 and 2023.
There aren't really a lot (any?) P2Panda web apps out there, most are desktop or mobile apps.
So, this change is being specifically request by the [LoRes Tech](https://lores.tech/) project in order to support our [LoRes Node](https://github.com/local-resilience-tech/lores-node/) app. We have a recipe drafted for this [here](https://codeberg.org/lores/lores-node-coop-cloud-recipe) and we will push that to the catalogue once this change is in.
It seems better to make this kiwix change as general as possible, which is why we called the flag `P2PANDA_ENABLED` rather than `LORES_NODE_ENABLED`. In practice if there was a larger ecosystem of such apps, we'd probably need to make the actual port numbers configurable.

This patch adds a METRICS_ENABLED configuration variables which,
when switched on, defines a metrics entrypoint and enables the
built-in prometheus metrics exporter. This allows the monitoring
stack to collect and show traefik metrics
