This change updates the logic to populate the options for the nvidia runtime configs added to containerd or crio from a default runtime if this is specified and a runc entry is not found. This allows the default runtime values for settings such as SystemdCgroup to be applied correctly. Signed-off-by: Evan Lezar <elezar@nvidia.com>
