change allowed renderers on per view basis

[sennierer]

currently the only way to configure renderers is to set the globally. We want a logic that allows to create a PersonCidocRenderer that is only active for the Person routes. Either use an attribute in the renderer class to configure and/or use the name of the class similar to the logic that the renderer now uses to find the correct serializer class.
function in the APIView class that can be used is get_renderer()
