isolate representation from content in GET request

Browse Source 
Container server representation of data (received from backend) is isolated
into `create_listing()` call. GET() method will call `create_listing()`
when it's ready to create a serialized object listing. It will allow us to
customize that representation: get different listing, if backend supports
more interesting queries, for example.
