grizzly: allow vm disk driver to be chosen per image

[Tom Fifield]

If https://review.openstack.org/#/c/20161/ is merged, a new feature is added to nova. New documentation should be created explaining the feature, and existing examples updated where necessary

This allows for an image in glance to be annotated with a
property describing the desired disk / cdrom bus type.

eg

# glance image-update \
--property disk_bus=ide \
--property cdrom_bus=ide \
f16-x86_64-openstack-sda

Valid bus values vary per the libvirt_type setting:

qemu/kvm: 'virtio', 'scsi', 'ide', 'virtio'
xen: 'xen', 'ide'
uml: 'uml'
