Feature/event recorder

[vishal-ramani]

Created new feature when application is started it will write an Kubernetes event in different conditions.
We can check those events via kubectl get events command.
Tested all scenarios as per our documentation with Kubernetes and OpenShift clusters.

Hi Vishal. Thanks for completing this task. I have some comments:

operator-application/controllers/application/deployment.go

In this file, the event "Created deployment" is not really a Warning in my opinion. Could you make this event type corev1.EventTypeNormal?

operator-application/controllers/application/conditions.go

In this file, I think you are logging the same message twice with code:

log.Info("Application resource status update failed.")
log.Info(CONDITION_MESSAGE_DELETECONDITION)

Also, the const definitions would be better defined in the variables.go file. However, if changing this would require a lot of repeat testing then it also fine to leave the consts where they are in conditions.go.

Thank you!
