Arguments to the <literal>thanos ${cmd}</literal> command.
Defaults to a list of arguments formed by converting the structured
options of <option>services.thanos.${cmd}</option> to a list of arguments.
Overriding this option will cause none of the structured options to have
any effect. So only set this if you know what you're doing!
