      This object is unique per request per thread.
  
      Library will retry according to this setting when App Engine Server
      can't call urlfetch, urlfetch timed out, or urlfetch got a 408 or
      500-600 response.
  
      Args:
        backoff_factor: exponential backoff multiplier.
        initial_delay: seconds to delay for the first retry.
        max_delay: max seconds to delay for every retry.
        min_retries: min number of times to retry. This value is automatically
          capped by max_retries.
        max_retries: max number of times to retry. Set this to 0 for no retry.
        max_retry_period: max total seconds spent on retry. Retry stops when
          this period passed AND min_retries has been attempted.
        urlfetch_timeout: timeout for urlfetch in seconds. Could be None,
          in which case the value will be chosen by urlfetch module.
        save_access_token: persist access token to datastore to avoid
          excessive usage of GetAccessToken API. Usually the token is cached
          in process and in memcache. In some cases, memcache isn't very
          reliable.
