matrix-nginx-proxy is going away and this is one of the features it
offered.

This feature will have no equivalent in our new Traefik-only
setup, although it's possible to implement it manually by using
`matrix_client_element_container_labels_additional_labels`

* Some fixes leftover code copeid over from whatsapp

* Got it to run and register

* Fixed service issue with docker image

* I now realize I need 2 roles wsproxy and imessage

* Got someting working, still rough

* Closer to working but still not working

* reverting ports

* Update main.yml

* Add matrix-nginx-proxy config for mautrix-wsproxy

* Changed

* Add back file

* fix for error hopefully

* Changed the the way nginx was recieved

* basically did not add anything ugh

* Added some arguments

* just trying stuff now

* Ugh i messed up port number

* Changed docs

* Change dns config

* changed generic secret key

* Testing new nginx proxy

* test

* Fix linting errors

* Add mautrix syncproxy to wsproxy for Android SMS

* WIP

* Move wsproxy to custom

* Squashed commit of the following:

* Fix linting errors

* Cleanup after merge

* Correct outdated variable names

* Enable both Android and iMessage with wsproxy

* Restructure wsproxy service defs and nginx config

* Fix linter errors

* Apply suggestions from code review

* Fix comments for documentation, volumes and ports

* Correct mount syntax

* Complete network and traefik support for wsproxy

* Remove wsproxy data_path

* Fix wsproxy service definitions

* Actually include syncproxy service

* Remove wsproxy PathPrefix, it needs a subdomain

There's no setting in the iMessage bridge that allows a path.
Also don't bind port by default, wsproxy has no TLS.
Syncproxy should never expose a port, it's only internal.

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)

We expect `--tags=start` to handle systemd reloading, so we don't need
to do it manually each time we install/uninstall a .service file.

- forego removing Docker images - it's not effective anyway, because it
  only removes the last version.. which is a drop in the bucket, usually

- do not reload systemd - it's none of our business. `--tags=start`,
  etc., handle this

- combine all uninstall tasks under a single block, which only runs if
  we detect traces (a leftover systemd .service file) of the component.
  If no such .service is detected, we skip them all. This may lead to
  incorect cleanup in rare cases, but is good enough for the most part.

This paves the way for installing other roles into `roles/galaxy` using `ansible-galaxy`,
similar to how it's done in:

- https://github.com/spantaleev/gitea-docker-ansible-deploy
- https://github.com/spantaleev/nextcloud-docker-ansible-deploy

In the near future, we'll be removing a lot of the shared role code from here
and using upstream roles for it. Some of the core `matrix-*` roles have
already been extracted out into other reusable roles:

- https://github.com/devture/com.devture.ansible.role.postgres
- https://github.com/devture/com.devture.ansible.role.systemd_docker_base
- https://github.com/devture/com.devture.ansible.role.timesync
- https://github.com/devture/com.devture.ansible.role.vars_preserver
- https://github.com/devture/com.devture.ansible.role.playbook_runtime_messages
- https://github.com/devture/com.devture.ansible.role.playbook_help

We just need to migrate to those.

Related to https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/1939

This commit adds a 'matrix-ntfy' role that runs Ntfy server in Docker with
simple configuration, and plumbing to add the role to the playbook.

TODO: documentation, self-check, database persistence.

Until now, we were leaving services "enabled"
(symlinks in /etc/systemd/system/multi-user.target.wants/).

We clean these up now. Broken symlinks may still exist in older
installations that enabled/disabled services. We're not taking care
to fix these up. It's just a cosmetic defect anyway.
