      * In 1.4, either that key or this key: `pods.beta.kubernetes.io/init-containers`,can be used.
    * When you GET an object, you will see both annotation keys with the same values.
      You can safely roll back from 1.4 to 1.3, and things with init-containers
      will still work (pods, deployments, etc).
    * If you are running 1.3, only use the alpha annotation, or it may be lost when
      rolling forward.
