- Stdin is now only passed to client-go exec credential plugins when it is detected to be an interactive terminal.

- The scheduling queue didn't notice any extenders' failures, it could miss some cluster events,
  and it could end up Pods rejected by Extenders stuck in unschedulable pod pool in 5min in the worst-case scenario.
  Now, the scheduling queue notices extenders' failures and requeue Pods rejected by Extenders appropriately. ([#122022](https://github.com/kubernetes/kubernetes/pull/122022), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

     as what's in them
   * For logic too complex to be expressed in a magic match, do the best
     you can here, then provide a Custom Detector for the rest
