To allow for CDI hooks to be added gradually we provide a generic no-op hook for unrecognised subcommands. This will log a warning instead of erroring out. An unsupported hook could be the result of a CDI specification referring to a new hook that is not yet supported by an older NVIDIA Container Toolkit version or a hook that has been removed in newer version.
