What happened
We would like to enhance the official Apache Airflow Helm chart v1.16.0 by adding first‑class support for HorizontalPodAutoscaler (HPA) and topologySpreadConstraints on the apiServer component. Currently, enabling these settings in values.yaml has no effect on the generated manifests.
What you think should happen instead
HPA for apiServer
When apiServer.hpa.enabled: true in values.yaml, render a HorizontalPodAutoscaler resource for airflow-api
Honor standard HPA parameters (minReplicas, maxReplicas, metrics) analogous to other components
TopologySpreadConstraints for apiServer
When apiServer.topologySpreadConstraints is defined, inject that block into Deployment.spec.template.spec of airflow-api
Use the same schema as elsewhere in the chart (e.g. scheduler, webserver)
How to reproduce
Add HPA or TopologySpreadConstraints parameter will trigger the error "apiServer: Additional property topologyKey is not allowed".
