[AWS] Create a S3 bucket with CORS settings

• CORS: Cross Origin Resource Sharing: defines how a client can interact with a resource, and what the client can and cannot do with that resource. Setting the CORS policy of our S3 bucket allows our client to communicate with the S3 bucket using the SignedURL pattern.

Bucket CORS Policy

You'll need this policy to create a bucket where we can use the SignedURL pattern.
