[Rados13]

Acknowledging the stipulations set forth:

• [x] I hereby confirm that a Pull Request involving updates to the Software Development Kit (SDK) has been smoothly merged, currently awaits processing, or is otherwise deemed unnecessary in this context.
• [x] I also affirm that another Pull Request, specifically addressing updates to the documentation body (commonly referred to as 'docs'), has either been successfully incorporated, is in the process of review, or is considered superfluous under the prevailing circumstances.

OpenAPI warning is fixed by how object S3Credentials is referenced. Error with AuthCache was fixed by providing AuthConfigAdapter, which is the way AuthCache is tested in ExAws.
