These changes replace the nvidia-container-runtime config options experimental and discover-mode with a single mode config option. Note that mode is now a string with a default value of "auto" and a mode value of "legacy" is equivalent to experimental == false. Signed-off-by: Evan Lezar <elezar@nvidia.com>
