Remove replicaCount from gateway to use external autoscaler (KEDA)

[omakeno]

Hello.

Can we have a new option to remove replicas from gateway manifests without creating HPA?
I'm using ScaledObject provided by KEDA as auto scaler of kong gateway ( in kong ingress chart ) for auto scaling instead of pure HPA to use AWS CloudWatch Metrics. This resource is created out of this chart and there is a conflict with deployment.spec.replicas value between this chart and external auto scaler.

I've tried to set gateway.replicaCount as null but it doesn't work because of this helm issue: helm/helm#9027

I suggest that set new value like autoscaling.type with default value hpa and enable to set it to external so that chart will not set replicas or create HPA resource.
