Hello, this is a first attempt to write a reactive app.
It should deploy a static website to AWS S3.
After creating the bucket, it should put the public bucket policy,
configure the bucket website and upload the files in parallel.

                putBucketPolicy
createBucket -> putBucketWebsite
                uploadFiles -> upload index.html
