As per earlier comment (see from tulir) the sequence has been changed.

Updated settings in template file:
* relay for any user
* user permissions only for HS domain users

Co-authored-by: Jan <31133207+Jaffex@users.noreply.github.com>

Permissions, when set in the template, will be augmented rahter than replaced when using matrix_mautrix_signal_configuration_extension_yaml. Therefore, permissions shall only be set in the defaults/vars.yml or in the HS specific vars.yml file

Enable / disable relay bot functionality as configuratoin paramter; set bridge permissions for base domain users to user level

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/806

We try to only use console logging (going to journald) for everything,
instead of logging things twice (or more).

While it's kind of nice having it, it's also somewhat raw
and unnecessary.

Having a good default and not even mentioning it seems better
for most users.

People who need a more exposed bridge (rare) can use
override the default configuration using
`matrix_mautrix_signal_configuration_extension_yaml`.
