Re: [PATCH 0/4] Implement virsh hypervisor-cpu-models

Allows for the query of hypervisor-known CPU models via the simple

are queried via the capabilities file. Each model is printed to the
terminal on its own line similar to the cpu-models command, and there
is no order to the listing.
This is just duplicating what we already expose to users in
virConnectGetDomainCapabilities / virsh domcapabilities.
eg
# virsh domcapabilities --xpath '//cpu//model/text()'

Yes, we currently have a virConnectGetCPUModelNames(), but when we
introduced the new QEMU-detectectable CPU support, we intended for
the virConnectGetDomainCapabilities API to replace the former use
case, so didn't add a new CPUModelNames API
