Enable Network Load Balancer (NLB) dualstack

* NLB subnets assigned both IPv4 and IPv6 addresses
* NLB DNS name has both A and AAAA records
* NLB to target node traffic is IPv4 (no change),
no change to security groups needed
* Ingresses exposed through the recommended Nginx
Ingress Controller addon will be accessible via
IPv4 or IPv6. No change is needed to the app's
CNAME to NLB record
