Serving at a path other than `/` doesn't work well yet.

Seems like this affected all "own webserver" deployments, which required
port exposure.

`playbook-managed-traefik` and `playbook-managed-nginx` were not affected.

It's probably unnecessary, as this user is only used in the borg container
internally, but.. It doesn't hurt to set it to `matrix`.

We'd like to auto-enable traefik-certs-dumper for these setups.

`devture_traefik_certs_dumper_ssl_dir_path` will be empty though,
so the role's validation will point people in the right direction.

With this, other roles (like Coturn, Postmoogle) will be able
to use SSL certificates extracted from Traefik
via https://github.com/ldez/traefik-certs-dumper

Check for empty string instead of Null to verify if an openid_server_name is pinned.

Applying the assumption, that synapse is always managed by this playbook.

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)

This just enables the endpoint, which is somewhat helpful, but not
really enough to scrape them. Ideally, we'd be injecting these targets
into the Prometheus scrape config too.
For now, registering targets with Prometheus is very manual
(`matrix_prometheus_scraper_postgres_enabled`, `matrix_prometheus_scraper_hookshot_enabled`, ..).
This should be redone - e.g. a new `matrix_prometheus_scrape_config_jobs_auto` variable,
which is dynamically built in `group_vars/matrix_servers`.

selectattr() returns a generator object, an iterator. This leads to an exception later, lists can't concated to iterators, only to other lists. So '| list' converts the iterator to a list and the script runs happily.

This extends the collection with support for seamless authentication at the Jitsi server using Matrix OpenID.

1. New role for installing the [Matrix User Verification Service](https://github.com/matrix-org/matrix-user-verification-service)
2. Changes to Jitsi role: Installing Jitsi Prosody Mods and configuring Jitsi Auth
3. Changes to Jitsi and nginx-proxy roles: Serving .well-known/element/jitsi from jitsi.DOMAIN
4. We updated the Jitsi documentation on authentication and added documentation for the user verification service.

Conduit update 0.5.0 fixed the issue, so this is no longer needed.
