Also, Job controller's constants for default backoff and maximal backoff are lowered down to 1s (from 10s) and 1min (from 6min), respectively. These constants are used to determine the backoff delay for the next Job controller sync in case of a request failure.

- Fix computing backoff delay when using Job pod failure policy, by including in the backoff delay calculation pod failures ignored from the backoffLimit counter.
  
  Also, compute the backoff delay more accurately for deleted pods. ([#119466](https://github.com/kubernetes/kubernetes/pull/119466), [@mimowo](https://github.com/mimowo)) [SIG Apps]
