This may proof useful to someone in the future.

We've had it on `matrix-nginx-proxy` before, but
our initial support for Traefik did not include any of these security
headers.

Previously, we had to run it at a subpath, like `/synapse-admin`.

We can now dedicate a whole domain and the `/` path to it, should we
wish to do so.

Previously, it had to go through matrix-nginx-proxy.
It's exposed to Traefik directly via container labels now

Update postmoogle 0.9.12 -> 0.9.13

Regression since 3d9aa8387e

* live SSL certificates reload on file changes (e.g., on automatic certs renewal)
* print all errors when trying connection to an SMTP server

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2474

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

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

Update coturn 4.6.1-r1 -> 4.6.1-r2

Previously, it had to go through matrix-nginx-proxy.
It's exposed to Traefik directly via container labels now.

restore borg prefixes

Supersedes https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2472

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`.

fix: missing endif

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

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

Reverse-proxy configuration changes and initial Traefik support

Upgrade Drapunir from 1.8.0 Beta to 1.8.0 release.

Add Draupnir to the Readme

Fix Dimension,Mjolnir and Drapunir crashing upon startup just to recover.

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.

The playbook tries to avoid such variables which are sometimes defined
and sometimes not. We'd rather not check for `is defined`.
