doc: Update references to image properties 

The 'architecture', 'hypervisor_type', 'hypervisor_version_requires' and
'vm_mode' image metadata properties have had new names for many cycles
now.

The example for the freshly renamed 'img_hv_requested_version' option
has been updated to show a Hyper-V example, since the Xen virt driver is
not tested and will likely be removed in the near future.

Filters hosts based on properties defined on the instance's image. It passes

For example, an instance might require a host that runs an ARM-based processor,
and QEMU as the hypervisor. You can decorate an image with these properties by

The image properties that the filter checks for are:
``architecture``
describes the machine architecture required by the image. Examples are
``hw_architecture``
Describes the machine architecture required by the image. Examples are
``i686``, ``x86_64``, ``arm``, and ``ppc64``.
``hypervisor_type``
describes the hypervisor required by the image. Examples are ``xen``,
``qemu``, and ``xenapi``.

This was previously called ``architecture``.
``img_hv_type``
Describes the hypervisor required by the image. Examples are ``qemu``,
``xenapi``, and ``hyperv``.
.. note::
``qemu`` is used for both QEMU and KVM hypervisor types.
``hypervisor_version_requires``
describes the hypervisor version required by the image. The property is
supported for Xen hypervisor type only. It can be used to enable support for
multiple hypervisor versions, and to prevent instances with newer Xen tools
.. versionchanged:: 12.0.0 (Liberty)
This was previously called ``hypervisor_type``.
``img_hv_requested_version``
Describes the hypervisor version required by the image. The property is
supported for HyperV hypervisor type only. It can be used to enable support for
multiple hypervisor versions, and to prevent instances with newer HyperV tools
from being provisioned on an older version of a hypervisor. If available, the
property value is compared to the hypervisor version of the compute host.
To filter the hosts by the hypervisor version, add the
``hypervisor_version_requires`` property on the image as metadata and pass an
``img_hv_requested_version`` property on the image as metadata and pass an
operator and a required hypervisor version as its value:
.. code-block:: console
$ openstack image set --property hypervisor_type=xen --property \
hypervisor_version_requires=">=4.3" img-uuid
$ openstack image set --property hypervisor_type=hyperv --property \
hypervisor_version_requires=">=6000" img-uuid
``vm_mode``
.. versionchanged:: 12.0.0 (Liberty)
This was previously called ``hypervisor_version_requires``.
``hw_vm_mode``
describes the hypervisor application binary interface (ABI) required by the
image. Examples are ``xen`` for Xen 3.0 paravirtual ABI, ``hvm`` for native
ABI, ``uml`` for User Mode Linux paravirtual ABI, ``exe`` for container virt
executable ABI.
.. versionchanged:: 12.0.0 (Liberty)
This was previously called ``vm_mode``.
