// Sets the cors configuration for your bucket. If the configuration exists,
// Amazon S3 replaces it. To use this operation, you must be allowed to perform the
// s3:PutBucketCORS action. By default, the bucket owner has this permission and
// can grant it to others. You set this configuration on a bucket so that the
// bucket can service cross-origin requests. For example, you might want to enable
// a request whose origin is http://www.example.com to access your Amazon S3
// bucket at my.example.bucket.com by using the browser's XMLHttpRequest
// capability. To enable cross-origin resource sharing (CORS) on a bucket, you add
// the cors subresource to the bucket. The cors subresource is an XML document in
// which you configure rules that identify origins and the HTTP methods that can be
// executed on your bucket. The document is limited to 64 KB in size. When Amazon
// S3 receives a cross-origin request (or a pre-flight OPTIONS request) against a
// bucket, it evaluates the cors configuration on the bucket and uses the first
// CORSRule rule that matches the incoming browser request to enable a cross-origin
// request. For a rule to match, the following conditions must be met:
//   - The request's Origin header must match AllowedOrigin elements.
//   - The request method (for example, GET, PUT, HEAD, and so on) or the
//     Access-Control-Request-Method header in case of a pre-flight OPTIONS request
//     must be one of the AllowedMethod elements.
//   - Every header specified in the Access-Control-Request-Headers request header
//     of a pre-flight request must match an AllowedHeader element.
//
// For more information about CORS, go to Enabling Cross-Origin Resource Sharing (https://docs.aws.amazon.com/AmazonS3/latest/dev/cors.html)
// in the Amazon S3 User Guide. The following operations are related to
// PutBucketCors :
//   - GetBucketCors (https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketCors.html)
//   - DeleteBucketCors (https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteBucketCors.html)
