 The only benefit SessionDelegate provides is to accompany URL respones with cache control headers which are not provided by the backend at the time of writing.
 (Cache control headers in responses let us use Foundation's NSURLCache abilities.)
 
 Once the backend implementation is changed to provide responses with cache control headers SessionDelegate should no longer be used.
 
 NOT THREAD SAFE - it should be used on the delegation queue of NSURLSession
