Feature Request: Update S3 module with AWS CLI 2.0 SSO integration

[RobertAlbus]

Hi Folks,

This issue in an unrelated project explains the same issue. Currently sccache doesn't pick up credentials when logged into AWS CLI v2 with SSO.

Is it possible to add support for this?

To set expectation: as we, Mozilla, don't need it currently, aren't going to work on it. So, contributions are welcome

[RobertAlbus]

Alright, I can look into it. Thanks.

Do you folks not use the S3 back end internally, or are you folks just still using AWS CLI V1? If it's the latter I encourage looking into upgrading.

We moved to gcp :)

Does anyone know if this should be part of opendal?

@Saruniks From what I recall when digging into this, the behavior is due to sccache integrating with opendal when opendal only supported environment variables for AWS auth. Today, opendal can automatically load credentials for valid AWS CLI sessions without the use of environment variables. It's been a while since I investigated this, so the details are a bit fuzzy but hopefully correct.
