Fix ctl control-config not being recognized

When parsing using the .argv interface to yargs the parser state is not
restored back to its pre-parsing state after the operation completes.
This causes a susequent reparse with argv to forget its commands and
respond with an unknown arguments error when trying to use the
control-config command to clusterioctl.  Fix by switching to use the
parse() interface which does restore the parser state after completing.
