Improvements to the deploy scripts

## Description:
1. Sometimes the deploy scripts output display "FAILURE" even when they succeed. (This may happen when a new deployment is not triggered because the image is already deployed.) This should be fixed.
Eg,
```
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: FAILURE
```

2. The Prod deploy scripts should prompt before running, to prevent inadvertently running it (which sometimes happens because all pipelines look similar in OpenShift).
