As I'm saying in the commit message - virt-viewer accepts --id, I don't 
expect ID completer to ever be implemented for virsh because as you say, 
domnames and/or uuids are accepted universally.

But adapting virt-viewer's completer is not going to be trivial anyway, 
so we might as well drop this :-)
