This change follows up #635 and lets end-users decide to disallow exemption rules defined as part of the config file or the controller annotations (whether none, any or both). The main use case here is to be able to prevent users with edit privileges over a controller to add a new exemption rule through an annotation which may obfuscate the actual policies we want to enforce.
