    Add `hide_hypervisor_id` flavor extra_spec
    
    Blueprint add-kvm-hidden-feature added the capability of hiding the kvm
    signature from guests. However, it was implemented only through an image
    property.
    
    A major reason for this feature is to allow passed-through Nvidia GPUs
    to work correctly. GPU pci-passthrough is specified on the flavor's
    extra_specs, without requiring an image with special properties.
    Therefore, hiding the KVM signature should also be specifiable through
    the flavor's extra_specs, in order to not require a special image for
    this use case.
    
    If the new flavor extra_spec is present and set to 'true', the libvirt
    driver will produce an additional element to hide kvm's signature on
    the vm, in the same way as with the image property
    `img_hide_hypervisor_id`.
