This adds the following --os-variant suboptions
* name=, short-id=
* id=
* detect=on|off
Functionally this does not change behavior, just adds explicit
sub options for behavior we already support

The --os-variant option naming is pretty crappy and mostly a historical
artifact. Ideally this would be named just `--os` but I'm afraid that
would cause confusion with libvirt's <os> XML
Add --osinfo as an alternate commandline naming. If we ever want to
transition documented use of --os-variant it will help to have the
alternative around for a few releases
