S3 Artifact Fetcher

An image that can be used as an init container to fetch artifacts for runner containers from S3.

The S3 URL to fetch the artifact from should be specified with the SOURCE_URL environment variable (e.g. "s3://some-bucket/some/folder). It should be a folder that will be synced into the container, rather than a singular file.

It will use the standard AWS environment variables for authentication (e.g. AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_DEFAULT_REGION).
