Create a classic static site deployment using cloudfront with a s3 origin. Provision, verify and
utilize a ACM certificate to enable (and force) https for cloudfront.
This assumes that the build resources are available at ./_site as a null_resource is used to
sync it to the s3 origin backing cloudfront. A IAM user and policy is provisioned prior to the
null_resource execution with least privilege access to the s3 bucket.
Note: The required terraform backend resources were manually provisioned.
