This change enables the experimental mode of the NVIDIA Container Runtime. If enabled, the nvidia-container-runtime.discover-mode config option is queried to determine how required OCI spec modifications should be defined. If "legacy" is selected, the existing NVIDIA Container Runtime hooks is discovered and injected into the OCI spec. Signed-off-by: Evan Lezar <elezar@nvidia.com>
