[GitHub] [airflow] Swalloow opened a new issue, #24103: Add support for KEDA HPA Config to Helm Chart

Swalloow opened a new issue, #24103:
URL: https://github.com/apache/airflow/issues/24103

   ### Description
   
   > When managing the scale of a group of replicas using the HorizontalPodAutoscaler, it is possible that the number of replicas keeps fluctuating frequently due to the dynamic nature of the metrics evaluated. This is sometimes referred to as thrashing, or flapping.
   https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/#flapping
   
   Sometimes clusters need to restrict the flapping of Airflow worker replicas.
   KEDA supports [`advanced.horizontalPodAutoscalerConfig`](https://keda.sh/docs/1.4/concepts/scaling-deployments/).
   It would be great if the users would have the option in the helm chart to configure scale down behavior.
   
   ### Use case/motivation
   
   KEDA currently cannot set advanced options.
   We want to set advanced options like `scaleDown.stabilizationWindowSeconds`, `scaleDown.policies`.
