Description

Currently, if a user specifies the source of a volume to be an image (e.g., Docker image), we only prepare the rootfs and mount it at 'container_path' in the container.

However, the rootfs itself is not sufficient to allow the executor to launch the docker container. We need the docker manifest as well to get the env, entry point, cmd information.

One solutions is to make container_path a directory containing two things: 1) rootfs, 2) manifest. But this is a breaking change, we might need to introduce a deprecation cycle for that.
