LFS Batch Api response is updated in huggingface-internal/moon-landing#15121 that - makes token refresh route mandatory (in field `action.href`) and puts CAS URL in the headers map; - sends a session id in the headers map; This PR builds on top of #498 and updates how client uses the information according to the above changes.
