 @abstract A RCTFBSDKGraphRequestConnectionContainer object can take in a batch of
 graph requests, send the requests in a graph request connection and return the responses of
 the requests in a connection callback.
 Note that the oject has a speical life cycle. It retains itself once the  `start` method is called.
 This is because the object needs to live long enough to forward along callbacks from each request.
 It will release itself when all callbacks are handled.
