Backup images from quay.io to S3

[hannes-ucsc]

Write a script that pulls out all of our organization's Docker images from quay.io and stores them as objects in a dedicated bucket in S3. Include the base images and the base images of the base images and so on. IOW, mirror the entire image DAG reachable from the organizational images.

Before writing the script research existing solutions for this.

Optional: Consider creating directory structure in S3 that would allow the bucket to be used as a Docker repository. You may have to enable the website feature of the S3 bucket. This would speed up our pipelines and reduce our cost.
