docs: <p>
  Deletes a pipeline, its pipeline definition, and its run history. AWS Data Pipeline attempts to cancel instances
  associated with the pipeline that are currently being processed by task runners.
  </p>
  <p>
  Deleting a pipeline cannot be undone. You cannot query or restore a deleted pipeline. To temporarily pause a
  pipeline instead of deleting it, call <a>SetStatus</a> with the status set to <code>PAUSE</code> on individual
  components. Components that are paused by <a>SetStatus</a> can be resumed.
