One use case is to use seperate disk for the registry storage. This
can prevent the rootfs from filling up.

The local Python executable for Kolla Ansible is changed to Python 3
because Kolla Ansible master no longer supports Python 2.

The default is still Python 2. This is a necessary prerequisite for using
the master branch of kolla-ansible, which requires Python 3.

In case of failures in kayobe-overcloud-centos, the error message fails
with:
kayobe/dev/functions: line 569: LOGDIR: unbound variable

Example:
https://zuul.opendev.org/t/openstack/build/ce1fadc3ee6d4842a599da57a670cc18

This can be reproduced with:
set -eu

if [[ -n ${LOGDIR} ]]; then
    echo "LOGDIR set"
else
    echo "else"
fi

Fix the error reporting with assigning an empty string to LOGDIR by
default.

We wrap doc8 to register the directives we use in our documentation.
Previously the 'app' argument was passed as None, however sphinx has
started to use the argument.

This change uses a mock object since we don't need to use the
application object.

* Remove unneeded configuration bits for doc building, the

Since I56533ead8357945a42b079fda7edbd9912fc135a (present in 7.0.0.0rc1),
seed VM provisioning fails due to a missing configdrive volume. The
problem is caused by the stackhpc.libvirt-vm role at version 1.8.0, and
the issue is described in
https://github.com/stackhpc/ansible-role-libvirt-vm/issues/45.

This change bumps the requirement for stackhpc.libvirt-vm to v1.10.0,
which includes a fix for the issue.

Since story 2006855, it is possible to specify a list of packages when
building IPA images. However, this introduced an issue in the case where
no packages are specified. See
https://github.com/stackhpc/ansible-role-os-images/issues/26.

This change fixes the issue by updating stackhpc.os-images role to
v1.7.0, which has a fix for this issue.

Kolla recently upgraded bifrost from 7.0.0 to 7.1.0 on the stable/train
branch. This switched to IPA builder to build the IPA image, and
introduced a rename of the IPA kernel file from ipa.vmlinuz to
ipa.kernel, which breaks overcloud provisioning. The iPXE kernel
download fails with a 404, since Kayobe introspection rules use
ipa.vmlinuz for the driver_info.deploy_kernel URL.

This change works around the issue by setting two Bifrost variables,
ipa_kernel and ipa_kernel_url, to reference the old kernel filename of
ipa.vmlinuz. This works both in the case where the image is downloaded
from a URL (ipa_kernel sets the destination file name), and where it is
built via 'kayobe seed deployment image build' (kayobe uses the legacy
ironic-agent DIB element rather than IPA builder, which creates a
hardlink to ipa.vmlinuz).

We chose the above approach rather than switching to IPA builder due to
it being a less risky change at a time close to release. A future
release of Kayobe should switch to IPA builder, but this will be a
larger effort.

In Kayobe hosts which are part of a Nova cell can be managed via the
existing controller and compute groups. However, since Nova Cells are
configured via group vars in Kolla Ansible we need some way of setting
these. We could pass vars through to Kolla Ansible host vars using
`kolla_overcloud_inventory_pass_through_host_vars` but the list of
variables which may be set on a per cell basis is large and undefined.

This change allows the user to directly specify Kolla Ansible group vars
as part of Kayobe config, allowing the deployment of Nova Cells by
Kayobe to be largely unchanged from the procedure documented in Kolla
Ansible.
