What would you like to be added

Add an explicit ConfigMap manifest for dns-autoscaler in Kubespray located next to roles/kubernetes-apps/ansible/templates/dns-autoscaler.yml.j2, and applied with the autoscaler Deployment.
The values should be configurable via Kubespray variables.

Why is this needed

dns-autoscaler intentionally does not update or reconcile its ConfigMap.
Upstream design treats the ConfigMap as user-owned input, and defaultParams are only a bootstrap / disaster-recovery fallback when the ConfigMap is missing (see upstream autoscaler issues #7 and #226).

Since Kubespray owns cluster configuration, it should define and manage the ConfigMap explicitly rather than relying on autoscaler runtime defaults.
