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.
