Which component are you using?:

/area helm-charts

Is your feature request designed to solve a problem? If so describe the problem this feature should solve.:

Default ndots (5) results in requests for e.g. autoscaling.eu-west-2.amazonaws.com being unnecessarily expanded over search domains e.g. autoscaling.eu-west-2.amazonaws.com.eu-west-2.compute.internal.

Describe the solution you'd like.:

Extend cluster-autoscaler chart besides dnsPolicy to allow tuning dnsConfig for cluster-autoscaler Deployment Pods

Describe any alternative solutions you've considered.:

• use (kyverno) policy to mutate cluster-autoscaler Pods
• fork chart and patch the fork

all of which are suboptimal
