feat: add `autoscaling.external`
PR Description
Currently there is no option to disable replicas in Statefulset and Deployment controller type, when I use KEDA to autoscale alloy based on number of metrics that alloy cluster pulls. I tried replicas: null but it also reset replica to 1 when upgrade helm. This could make some downtime (less than 30s).
This PR is to add autoscaling.external variable to remove replicas when external autoscaler is used.
