  // Example: when this is set to 30%, the old RC can be scaled down to 70% of desired pods
  // immediately when the rolling update starts. Once new pods are ready, old RC
  // can be scaled down further, followed by scaling up the new RC, ensuring
  // that the total number of pods available at all times during the update is at
  // least 70% of desired pods.
