// matchPodFailurePolicy returns information about matching a given failed pod
// against the pod failure policy rules. The information is represented as an
//   - optional job failure message (present in case the pod matched a 'FailJob' rule),
//   - a boolean indicating if the failure should be counted towards backoffLimit
//     (and backoffLimitPerIndex if specified). It should not be counted
//     if the pod matched an 'Ignore' rule,
//   - a pointer to the matched pod failure policy action.
