hyper-v requires additional enlightments to function in kvm

Currently, when an image has os_type specified as windows, Nova enables a limited set of hyper-v enlightenments to the virtual machine. These enlightenments include hv-relaxed,hv-vapic,hv-spinlocks=0x1fff,hv-vendor-id=1234567890ab. With only these options enabled, Windows Server 2019 (possibly older versions as well) with not boot and immediately locks upon booting if the hyper-v role is installed in the instance.

In testing, if the following enlightenments are also enabled in addition to the ones that are already enabled, the problem is resolved and nested virtualization is able to function using hyper-v on a nova compute node running KVM.
