[libvirt] [ v3 1/4] Schema: Introduce XML schema for network-backed loader and nvram elements.

Today, 'loader' and 'nvram' elements are supposed to be backed by a local disk. Given that NVRAM data could be network-backed for high availability, this patch defines XML spec for serving loader & nvram disks via the network.
