[task/acm-refactor] Refactor the ACM classes to have a common interface.
They are now refered to as cache drivers rather than ACM classes. The additional utility functions from the original cache class have been moved to the cache_service. The class loader is now instantiated without a cache instance and passed one as soon as it is constructed to allow autoloading the cache classes. PHPBB3-9983
