Entity Provider Callbacks

These callbacks will be used to support the $expand query option. Callbacks have to implement the ODataCallback as a marker.
To support an expanded entry the OnWriteEntryContent interface has to be implemented.
To support an expanded feed the OnWriteFeedContent interface has to be implemented.

All callbacks are registered for a navigation property in a HashMap<String as navigation property name, callback for this navigation property> and will only be called if a matching $expand clause is found.
