Public bug reported:

When listing role assignments, we have the option to filter them by actor, target and role.
As Henry Nash pointed out at [1] , the current implementation uses the standard filtering the V3.wrap_collection. Given the large number of individual assignments, this is pretty inefficient. 

The controller must pass the filters into the driver call, so that the list size is kept a minimum.
For example, if the user wants to filter role assignments by project X, the driver will query the DB only selecting the role assignments where target_id = X.id, instead of querying everything and returning the result to be filtered by the controller.
