**Description**

Add the missing AWS Operators for the three (get/put/delete) AWS S3 bucket tagging APIs, including testing.

**Use case / motivation**

I am looking to add an Operator that will implement the existing API functionality to manage the tags on an AWS S3 bucket.

**Are you willing to submit a PR?**

Yes
