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.
