 After the boostrap, the podinfo deployment will be scaled to zero and the traffic to `podinfo.test` will be routed to the primary pods. To keep the podinfo deployment
 at 0 replicas and pause auto scaling, Flagger will add an annotation to your ScaledObject: `autoscaling.keda.sh/paused-replicas: 0`.
 During the canary analysis, the annotation is removed, to enable auto scaling for the podinfo deployment.
