  Marks a custom action as deleted. PollForJobs for the custom action will fail after the action is marked for
  deletion. Only used for custom actions.
  </p>
  <important>
  <p>
  To re-create a custom action after it has been deleted you must use a string in the version field that has never
  been used before. This string can be an incremented version number, for example. To restore a deleted custom
  action, use a JSON file that is identical to the deleted action, including the original string in the version
  field.
