> Currently DataContext/BaseContext are trying to guess their QueryCache from the parent
or instantiate the default. We should start using the injection for that. Since injection
mechanism is not configured in ROP yet, this implementation will do the following:
> 1. Do QueryCache injection at the BaseContext (superclass) level. 
> 2. Remove custom loading code from DataContext
> 3. Move BaseContext custom loading code to CayenneContext
> 4. In the factory implementation wrap the underlying cache in NestedQueryCache for ObjectContexts
(and for shared cache?) instead of instantiating a new cache for each child context. This
would allow centralized cache groups management
