Make `review-deploy` display some debug output when it fails
We recently caught a legitimate bug in the review-deploy
job but that wasn't obvious what the cause was at first sight.
The issue was https://gitlab.com/gitlab-org/gitlab-ce/issues/62125.
We should make easier to understand what is the root cause of a failed deployment for instance by:
- Displaying
helm status
at the end of the job - Displaying
kubectl get pods --namespace<namespace> -l release=<release>
at the end of the job - Displaying
kubectl logs <pod>
at the end of the job
