WT-8653 added an S3-hello-world extension. Make changes to create and list objects in a statically configured S3 bucket. The objective is to do the python test changes that are required to:
- Allow multiple tests on S3 to be run simultaneously from the same user, and from the different user.
- Make sure failing (or passing) tests do not leave artefacts.
- Explore and configure retention policies around test objects.
- For debugging, should failing tests leave and preserve artefacts and not the passing tests. If yes when and how would these artefacts be cleared.
