Add age to AnalysisRun printer columns

[yashmehrotra]

Summary

Add an AGE parameter to AnalysisRun printer columns for ease of viewing

Use Cases

When debugging why a canary rolled back, doing a kubectl get of AnalysisRun returns just the name and status. While the name being composed of the replicaset makes things easier, I found that adding the Age parameter helps tremendously.

The only change we need to make is to add this to the additonalPrinterColumns in the CRD

    - jsonPath: .metadata.creationTimestamp
      name: Age
      type: date

If you are interested in having this change, I'd love to contribute 😄

I added this in my cluster's deployment and it helped the team a lot. This is how it looks:
