Merge pull request #51153 from clamoriniere1A/feature/job_failure_policy_controller
Automatic merge from submit-queue Job failure policy controller support **What this PR does / why we need it**: Start implementing the support of the "Backoff policy and failed pod limit" in the ```JobController``` defined in https://github.com/kubernetes/community/pull/583. This PR depends on a previous PR #48075 that updates the K8s API types. TODO: * [X] Implement ```JobSpec.BackoffLimit``` support * [x] Rebase when #48075 has been merged. * [X] Implement end2end tests implements https://github.com/kubernetes/community/pull/583 **Special notes for your reviewer**: **Release note**: ```release-note Add backoff policy and failed pod limit for a job ```
