This resolves an issue where based on the results of one request,
the client will create an Instance class as a subclass of StateFullObject
then, based on the results of another request try to create an Instance
as a subclass of ActionObject, causing a superclass mismatch error.
ACK. Nice catch Tobi.
This patch groups the dynamic classes inside nested containing classes
inside DeltaCloud::API, preventing collisions.
