Returns a list of CLI option names required by this command.

The main console appication may use this list to output an eror (and exit) if any of the returned names are not found in the parsed CLI options.

The (already parsed) parser may be used adjust the returned required options depending on the value of other options. For example, the logger command only requires the --mode option if the --command option is start.

This base implementation simply returns an empty list. Derived classes should override this function to include any required options.
