Optimize the read-reasource-description payload

When a presenter is loaded for the first time, a r-r-d op is executed for every annotated required resource:

...        
operation.get(OP).set(READ_RESOURCE_DESCRIPTION_OPERATION);
operation.get(OPERATIONS).set(true);
operation.get(ACCESS_CONTROL).set(COMBINED_DESCRIPTIONS);
...

We use COMBINED_DESCRIPTIONS because we need both the access control information, but also the meta data for the attributes. What we don't need upfront is the descreption. The description makes the payload big. Hence it would be great to have another option like META-DATA which works like COMBINED_DESCRIPTIONS but without descriptions.
