CLOUDSTACK-8424: Add cpu features if guest.cpu.features is set
This improvements checks for "guest.cpu.features" property which is a space
separated list of cpu features that is specific for a host. When added, it
will add <feature policy='require' name='{{feature-you-listed}}'/> in the
<cpu> section of the generated vm spec xml.

> Right now, if we want to enable CPU features such as "vmx" on KVM guest vms,
> there is no way to do that. The improvement is to add a flag in
> agent.properties per host that is specific for a host using the property
> "guest.cpu.features=vmx vme" where features are space separated. This will
> lead to adding <feature policy='require' name='vmx'/> in the <cpu> section of
> the created XML. This can be useful to start guest VMs that need vmx, the
> primary purpose is to provision nested virtualized kvm hosts on a kvm host to
> test CloudStack :)
