Dmitry Tantsur 81f583f69b devstack: use CentOS 9 for DIB IPA builds
Additionally bumps CPU model to host-model as centos9 builds now
require a subset of CPU processors which include advanced features.
Host-model also allows for the VM to still start when running with
pure qemu, as opposed to KVM passthrough.

Building or downloading a deploy ramdisk image
==============================================
Ironic depends on having an image with the
:ironic-python-agent-doc:`ironic-python-agent (IPA) <>`
service running on it for controlling and deploying bare metal nodes.
Two kinds of images are published on every commit from every branch of
:ironic-python-agent-doc:`ironic-python-agent (IPA) <>`
* DIB_ images are suitable for production usage and can be downloaded from
https://tarballs.openstack.org/ironic-python-agent/dib/files/.
* For Train and older use CentOS 7 images.
* For Ussuri and up to Yoga use CentOS 8 images.
* For Zed and newer use CentOS 9 images.
.. warning:: CentOS 7 master images are no longer updated and must not be
used.
.. warning:: The published images will not work for dhcp-less deployments
since the simple-init_ element is not present. Check the DIB_
documentation to see how to build the image.
* TinyIPA_ images are suitable for CI and testing environments and can be
downloaded from
https://tarballs.openstack.org/ironic-python-agent/tinyipa/files/.
