Article deletion - time should be configurable
Since the latest update articels can only be deleted within 10 minutes.
see - https://github.com/zammad/zammad/issues/2687
This should be configurable.
- on / off
- time adjustable
As mentioned in #2687 - Administrators should still be able to delete articles.
This is also missing.
Better solution than Administrator would be if that could be set in the roles.
