[chart] support configuring dnsConfig #4154
Description
Describe the feature you are requesting
Provide dnsConfig option for aws-load-balancer-controller Deployment Pods https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/#pod-dns-config
Motivation
with default ndots (5), requests to e.g. ec2.eu-west-2.amazonaws.com get unnecessarily expanded over search domains e.g. result in dns query for ec2.eu-west-2.amazonaws.com.eu-west-2.compute.internal.
Describe the proposed solution you'd like
Just like dnsPolicy was supported #2324 add equivalent for dnsConfig.
Describe alternatives you've considered
- (kyverno) policy to mutate aws-load-balancer-controller Pods
- forking chart and patching the fork
both of which are suboptimal
