Fixup for ba51997f7b

We redefine these variables in `group_vars/matrix_servers`, but it's better
to have some defaults in the role as well.

Currently, Synapse workers ignore the X-Forwarded headers, which leads to internal Docker IP addresses randomly appearing in the users' device list.

This adds the `x_forwarded: true` option to the worker config, fixing the issue.

Fixup for 5eff67371d - https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/1884

matrix-corporal 2.3.0 supports Synapse v1.61.0 (which removed
communities/groups support).

Based on mautrix-whatsapp, as that's what the bridge software is based on.

Debug logs are inappropriate for production use.

Fixes #1873

The same logs still go to the systemd journal.

This is a poor way to do things though. It may break again in the future.
matrix-registration is a poorly maintained project and should likely be removed from the playbook.

Now that https://github.com/digitalentity/matrix_encryption_disabler/pull/9
has been merged, we can get the module from there.

As an alternative, we should probably find a way to run one or a few
more generic workers (which will handle appservice and user_dir stuff) and
update `homeserver.yaml` so that it would point to the name of these workers using
`notify_appservices_from_worker` and `update_user_directory_from_worker` options.

For now, this solves the deprecation, so we can have a peace of mind
going forward.

We're force-setting these worker counts to 0, so that we can clean up
existing homeservers which use these worker types. In the future, these
options will either be removed or repurposed (so that they transparently
create more generic workers that handle user_dir/appservice loads).

* add `NOENCRYPTION` option
* fix race condition on thread start
* fix greetings messages
* updated deps

Line 10, which sets the tag to which docker version to pull was reverted from `v1.1.15` to latest. This gets the playbook working again

When using LDAP simple bind, the `bind_dn` and `bind_password`
configuration values must not be present.
