Cédric Jeanneret 6645f47db4 Ensure cloud-init is configured to generated host keys
It may happen a base image has an edited version of cloud-init
"cloud.cfg" that prevents the host keys to be generated.

While it didn't represent an issue with older releases of cloud-init,
starting cloud-init-22 this isn't true anymore.

Before that release, an sshd-keygen@.service was present and called by
sshd-keygen.target (which was called by sshd.service), and we ended up
with ssh host keys in any cases - either generated from cloud-init, or
generated by sshd-keygen.service.

But cloud-init-22 introduced an edition to the sshd-keygen.service,
making it check for the presence of cloud-init service, and preventing
this sshd-keygen to kick in this case.

So we'd better ensure cloud-init is able to generate the keys, else
we'll be in a bad state, since it's instructed to remove the ones
present.

Image building tools for OpenStack
==================================

``diskimage-builder`` is a flexible suite of components for building a
wide-range of disk images, filesystem images and ramdisk images for
use with OpenStack.

This repository has the core functionality for building such images,
both virtual and bare metal. Images are composed using `elements`;
while fundamental elements are provided here, individual projects have
the flexibility to customise the image build with their own elements.

For example::

  $ DIB_RELEASE=bionic disk-image-create -o ubuntu-bionic.qcow2 vm ubuntu

will create a bootable Ubuntu Bionic based ``qcow2`` image.

``diskimage-builder`` is useful to anyone looking to produce
customised images for deployment into clouds. These tools are the
components of `TripleO <https://wiki.openstack.org/wiki/TripleO>`__
that are responsible for building disk images. They are also used
extensively to build images for testing OpenStack itself, particularly
with `nodepool
<https://docs.openstack.org/infra/system-config/nodepool.html>`__.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.

Full documentation, the source of which is in ``doc/source/``, is
