This allows us to eliminate the companion and decrease overhead for
simple servers which do not use workers.

This saves up 1 container network and avoids going through extra proxies
unnecessarily.

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 also updates validation tasks and documentation, pointing to
variables in the matrix-synapse role which don't currently exist yet
(e.g. `matrix_synapse_container_labels_client_synapse_admin_api_enabled`).

These variables will be added soon, as Traefik labels are added to the
`matrix-synapse` role. At that point, the `matrix-synapse-reverse-proxy-companion` role
will be updated to also use them.

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`

This is completely untested.

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.

`matrix_media_repo_identifier` is already defined in the role defaults,
which is a better role to have it anyway.

It seems like connectivity is problematic, even though the networks
appear to be configured correctly:

> [ioredis] Unhandled error event: Error: connect ECONNREFUSED 172.22.0.2:6739
> at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1595:16)

For now, I disable pointing the queue host to Redis to avoid it.
It should be investigated.

People who enable Hookshot's new experimental encryption may encounter
this also.

    draft encryption support for hookshot

Related to e3375d56f3

Currently v3.0.0 tested with no issues.
So remove matrix_user_verification_service_docker_image from groups_vars.

/.npm must be writable or an error will be reported.

It would work even without explicitly passing `jitsi_user_username` as
auto-detection logic will run. Passing it explicitly spares the Jitsi
role some work.

Related to:

- https://github.com/mother-of-all-self-hosting/ansible-role-jitsi/pull/2
- https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2974#issuecomment-1784256903

Only available since v16.0-2 of the Postgres role.

Related to #2851 

Fixes #2861

`devture_traefik_provider_configuration_extension_yaml` should not be
set automatically by the playbook. It's a variable to be used by users.

Moreover, setting for for everyone (not just people who have additional JVBs)
means that for most people the following error will be produced:

> 'dict object' has no attribute 'jitsi_jvb_servers'

.. as detailed in https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2844

Fixes a regression introduced in: https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2842

Traefik wasn't proxying /colibri-ws/jvb-X/ to additional jvbs. This
fixes it.

* 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

Co-authored-by: Slavi Pantaleev <slavi@devture.com>

* 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.
