This change attempts to load the nvidia, nvidia-uvm, and nvidia-modeset kernel modules before generating the automatic (jit) CDI specification. The kernel modules can be controlled by the nvidia-container-runtime.modes.jit-cdi.load-kernel-modules config option. If this is set to the empty list, then no kernel modules are loaded. Errors in loading the kernel modules are logged, but ignored. Signed-off-by: Evan Lezar <elezar@nvidia.com>
