Set bucket labels

To add or modify labels applied to a bucket, you make a PUT request that is scoped to the desired bucket, and you use the tagging query string parameter along with a <Tagging> element in the request body.

Note: When making a PUT request with the tagging query string parameter, existing bucket labels are removed unless they are included in the body of the PUT request.
