Enabling IPv6 support

[ronaldtse]

We received a kind report from @tambry on the following:

I recently happened on the RNP website while I had only IPv6 enabled. Unfortunately it lacks IPv6 support and thus failed to load.
Since it seems to use CloudFront, fixing this should be as easy as enabling IPv6 on the CloudFront distribution and creating an AAAA ALIAS record pointing to it.
Might be something you'll want to fix.

This we need to fix in the underlying Terraform module (https://github.com/riboseinc/terraform-aws-s3-cloudfront-website) and updating the site to use the new module with the AAAA records. The S3 bucket in the module needs to also have IPv6 enabled.

@phuonghuynh can you help this? Thanks!

The following features are not currently supported when accessing an S3 bucket over IPv6:

@ronaldtse S3 Static website not support IPV6 acess for now, https://docs.aws.amazon.com/AmazonS3/latest/dev/ipv6-access.html

PR for Cloudfront IPV6 support submitted here

Tested using a free online IPV6 test sevice for the sample site http://mysite.booppi.website.

@phuonghuynh I see. Does this mean the cloudfront ipv6 works with S3 ipv4?

Yes, the PR added new variable to suport it ("true" is default), git hash
