Clark Boylan 788224cfe0 Don't remove packages that are requested to be installed
Recently the source-repositories element was updated [0] to set git as a
build-only dep. This is fine if you don't request to install git
elsewhere as a regular package install [1]. If you mix the two then git
gets uninstalled when you expect it to be installed.

Address this by checking if a package is already requested to be
installed when we find a removal or build-only request. Similarly remove
a package from the uninstall list if we ask for it to be installed
normally. This means that explicit installs override any cleanup
actions.

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
published at:
