This change adds the discovery of DRM devices associated with requested devices. This means that the /dev/dri/card* and /dev/dri/renderD* devices associated with each requested NVIDIA GPU are injected into the container and that the /dev/dri/by-path symlinks associated with these devices are created in the container.
