Despite what the help text for this options says, the nova API only
accepts boolean values for this value and has done so since at least the
introduction of the 2.1 microversioned API. While it would be nice to
convert '--config-drive' to a boolean flag, we'd need to be able to
retain temporary support for people passing arguments. 'nargs=?' [1]
looks promising but it has an annoying tendency to swallow a positional
argument following it [2]. Since that is not an option, we have to live
with a new config option, '--use-config-drive' and a '--no-config-drive'
counterpart.
