[virt-tools-list] [PATCH 3/3] add a checkbox for cpu host-model mode, remove 'copy' button

Guannan Ren gren at redhat.com

If the host-model is selected, disable the cpu model drop down
and features list. They still show what exact configuration the
host-model is using.
For the old libvirt which doesn't support <cpu mode='host-model'/>
virt-manager still copy cpu configs from caps XML to domain XML.
If a certain libvirt version supports host-model, but the UPDATE_CPU
flag doesn't exist, a WARN image will show up on UI to give a hint.
