  // Calls to ::validateConfiguration are made very early, and because of this
  // it would be too expensive to do any live validation of the given
  // token and service_id. Instead, we only verify that they look right and
  // let ::fastlyResponseData() make calls to ::setTemporaryRuntimeError()
  // so that cache invalidation gets suspended in case of bad API creds.
