In this context, there is no container id, maybe we can fix
preparePrivilegedOperation to accept null instead of passing system time to
make this more readable.

If I remember correctly, preparePrivilegedOperator requires that string to
construct the filename of the docker command file. I can re-check. We can think
of a better string to pass, possibly the "image name and the version".

> {{LinuxContainerExecutor}} is for container operations. DockerImagesCommand
> is independent of any container. The image localizer acts as a service that
> will localize docker images and maintain an image cache. Other components can
> use this to query about the images on the node.
