Closes #11381

This PR implements #11381 enhancement to expose application labels on k8s events generated by Argo CD.

Change:
This PR introduces two new key resource.includeEventLabelKeys & resource.excludeEventLabelKeys in argocd-cm configmap which takes in a comma separated string of label keys.
For any events generated for Applications containing the label keys specified in resource.includeEventLabelKeys, the controller adds the matched label onto the event thus establishing an easy link between the event and the application to filter-out/process later using labels. The specified label keys are matched against the Application and it's AppProject labels. In case of conflict between labels on Application and it's AppProject, the Application label values are prioritised and added to the event.
Furthermore, labels specified in resource.excludeEventLabelKeys are removed from the event labels, if they were included.

Sample output:

$ kubectl get events -l env=dev --show-labels

I think this is a great start, to make it feature complete can we handle the include/exclude use cases?

Thanks for @todaywasawesome & @leoluz for your inputs. I have incorporated your suggestions by introducing two new keys resource.includeEventLabelKeys & resource.excludeEventLabelKeys in argocd-cm configmap and adding wildcard support to make it feature complete. The PR is ready for review.

Was wondering if we had a better context than the TODO() one here and elsewhere.
