> Mounting files or directories from the host is one way of passing
> configuration and other information into a docker container. We could allow
> the user to set a list of mounts in the environment of ContainerLaunchContext
> (e.g. /dir1:/targetdir1,/dir2:/targetdir2). These would be mounted read-only
> to the specified target locations.
> Due to permissions and user concerns, for this ticket we will require the
> mounts to be resources that are in the distributed cache.
