I've pushed this now with some changes. The main thing is that the cli
is now only

  --features kvm.hint-dedicated.state=on|off

As this matches the actual XML names. That is the pattern we are
following with all new XML command line pieces so it's easier for users
to reason about the virt-install/virt-xml naming given any XML name. I
tweaked the commit message to match this new naming

And I made small changes to the tests to ensure the test suite doesn't
fail on non-latest libvirt

Thanks,
Cole
