Allow job parallel running instead of replace

When using concurrentPolicy=Replace and the job failed but haven't reach the backoff
limit, the new job will replace the original one if the schedule time is
less than the sum of the backoff time.

It causes a problem that the job alert
`kube_job_status_failed{job_name=~"refresh-credential.*",reason="BackoffLimitExceeded"}` can't be fired.
