Add URL redirections setup to CloudFormation template

[tschaffter]

About redirections, the final solution uses a single S3 bucket named nlpsandbox.io. Route 53 has two A records, nlpsandbox.io and www.nlpsandbox.io that both redirect to the CloudFront distribution connected to the S3 bucket.

Just noticed the description of the repo:

AWS CloudFormation template for deploying the NLP Sandbox benchmarking infrastructure

Since the redirections are not needed for the benchmarking infra, should this configuration live somewhere else?

I updated the description @tschaffter - the templates should definitely live in this repository. That being said, since the S3 bucket has been created already, the templates can't be added since it will cause a "s3 bucket already exists error".

@thomasyu888 Feel free to delete the bucket if needed. It's preferable to do this before the launch. For reference, the current redirection rules are listed below.

Cloudfront Distribution CNAMEs is not supported: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-distribution-distributionconfig.html. So will resort to the manual creation of the cloudfront resource.

@thomasyu888 The URL redirections are currently broken. I guess I may expect this as long as this ticket is open. I looked at the AWS account and so all the resources (R53 records, CF distribution, S3 buckets) and everything is there so I'm not sure why the redirections are broken.

@tschaffter The redirections are working again. The Cloudfront distribution was disabled - I thought I enabled it again, but my internet must have cut out.
