Use aws cli instead of minio mc and bucket variables
Prepare for a world of multiple (cloud) S3 providers at the same time.
- standardize on the aws cli and remove minio client from tests
- provide functions to download and upload to an S3 bucket
- unit tests for those functions
- switch the prepare stage to use bucket variables
- switch the ccache to use bucket variables
