Libvirt domain XML allows only local filepaths to specify a loader element
or its matching NVRAM. Given that VMs may themselves move across hypervisor
hosts, it should be possible to allocate loaders/NVRAM disks on network storage
for uninterrupted access.

This series extends the loader & NVRAM disk elements to be described as
virStorageSource* elements, as discussed in :
https://www.redhat.com/archives/libvir-list/2018-March/msg01721.html

Sample XML with new annotation:

<loader readonly='yes' type='pflash' backing='file'>
  <source file='/usr/share/OVMF/OVMF_CODE.fd'/>
</loader>
<nvram backing='network'>
  <source protocol='iscsi' name='iqn.2013-07.com.example:iscsi-nopool/0'>
    <host name='example.com' port='6000'/>
  </source>
</nvram>
