redhat/configs/evaluate_configs: Add find dead configs option
Add an option to evaluate_configs to find configs that are no longer
referenced in the configs. The "-D" command only find unreferenced
configs and there is no guarantee that the resulting changes will result
in valid config generation. ie) Additional changes may be required after
running the -D command.
Add an option to find dead configs.
