'-cdrom' is the 'other argument' == 'Non-parameter argument'?
We can use a enum state.
| { 'enum': 'ArgumentStateType',
| 'data': ['no-argument', 'unspecified-parameters-argument',
| 'non-parameter-argument']
| }
|
| { 'type': 'CommandLineOptionInfo',

['CommandLineParameterInfo'],
| '*argument-state': 'ArgumentStateType' } }

How about balloon? we should treat as 'taking unspecified parameters'?
"-balloon none disable balloon device\n"
"-balloon virtio[,addr=str]\n"
I think we should treat as 'unspecified parameters'
I think we can only check this from help message in qemu-options.hx,
is it a stable/acceptable method?
We introduce query-command-line-options command to avoid libvirt to
check qemu commandline information by scanning qemu's help message,
it's not strict & stable.
