This also adds labels for Synapse. Support for other homeservers and
components will be added later.

Downsides: decreasing security slightly due to less networking isolation

Benefits:

- decreased complexity
- having a generically-named `matrix-addons` network we may use for other things now (client apps, etc.)
- not exhausting the container networks pool with 2 (or more) networks and using just 1

This is still very far from usable.

Various bridges and bots are still talking to
`matrix-nginx-proxy` instead of the new `matrix-homeserver-proxy` role.
These services need to be reworked. While reworking them,
various cleanups are being done as well as adding Traefik-labels to
those that need them.

* 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* Correct outdated variable names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.

Starting from version `0.6.0` conduit natively supports some sync v3 (sliding-sync) features.

https://gitlab.com/famedly/conduit/-/releases/v0.6.0
https://gitlab.com/famedly/conduit/-/merge_requests/501

Partially reverts 0a6b934a44.

`preferred_domain` is only used by Element and does not apply to the
`/.well-known/matrix/client` file.

Related to: https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2375#issuecomment-1655758296

* one var to control encryption across all bridges

* move var to matrix-base

This allows people to try out the new Element X clients, which need to
run against the sliding-sync proxy (https://github.com/matrix-org/sliding-sync).

Supersedes https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2515

The code is based on the existing PR (#2515), but heavily reworked. Major changes:

- lots of internal refactoring and variable renaming

- fixed self-building to support non-amd64 architectures

- changed to talk to the homeserver locally, over the container network (not
  publicly)

- no more matrix-nginx-proxy support due to complexity (see below)

- no more `matrix_server_fqn_sliding_sync_proxy` in favor of
  `matrix_sliding_sync_hostname` and `matrix_sliding_sync_path_prefix`

- runs on `matrix.DOMAIN/sliding-sync` by default, so it can tried
  easily without having to create new DNS records

The variable was necessary when multiple playbooks could have
potentially tried to manage a shared `devture-traefik.serivce` systemd service
and shared `/devture-traefik` directory.

Since adcc6d9723086f65f1a72, we use our own `/matrix/traefik`
(`matrix-traefik.service`) installation and no conflicts can arise.
It's safe to always enable the role, just like we do with all the other roles.

The migration is automatic. Existing users should experience a bit of
downtime until the playbook runs to completion, but don't need to do
anything manually.

This change is provoked by https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2535

While my statements there ("Traefik is a shared component among
sibling/related playbooks and should retain its global
non-matrix-prefixed name and path") do make sense, there's another point
of view as well.

With the addition of docker-socket-proxy support in bf2b54080789f7e,
we potentially introduced another non-`matrix-`-prefixed systemd service
and global path (`/devture-container-socket-proxy`). It would have
started to become messy.

Traefik always being called `devture-traefik.service` and using the `/devture-traefik` path
has the following downsides:

- different playbooks may write to the same place, unintentionally,
  before you disable the Traefik role in some of them.
  If each playbook manages its own installation, no such conflicts
  arise and you'll learn about the conflict when one of them starts its
  Traefik service and fails because the ports are already in use

- the data is scattered - backing up `/matrix` is no longer enough when
  some stuff lives in `/devture-traefik` or `/devture-container-socket-proxy` as well;
  similarly, deleting `/matrix` is no longer enough to clean up

For this reason, the Traefik instance managed by this playbook
will now be called `matrix-traefik` and live under `/matrix/traefik`.

This also makes it obvious to users running multiple playbooks, which
Traefik instance (powered by which playbook) is the active one.
Previously, you'd look at `devture-traefik.service` and wonder which
role was managing it.

This new role also adds native Traefik support and support for other
(non-`amd64`) architectures via self-building.

* fix: only add element related entries to client well-known if element is enabled

* Fix matrix-base/defaults/main.yml syntax

We need this to control whether `('matrix-' + matrix_homeserver_implementation + '.service')`
would get injected into `devture_systemd_service_manager_services_list_auto`
