After reestructuring `deb-local-binary` into multiple binary
repositories, one for each layer, the image build now has access to
three repositories by default:
* deb-local-binary;
* deb-local-binary-containers;
* deb-local-build.
Although these repositories are sufficient for the vast majority of
images, there are some, such as `stx-openstackclients`, that require
dependencies that are found in another repository:
`deb-local-binary-openstack`.
This image, as the name suggests, contains all the OpenStack clients
currently supported by the StarlingX OpenStack application.
As one can see in [1], although most clients are installed in the form
of pip packages, i.e., through wheel files collected from the upstream
indexes, there are two clients that are installed in the form of
distribution packages:
* python3-cinderclient;
* python3-openstackclient.
The reason why they are installed as distribution packages is because
they have patches that are specific to StarlingX OpenStack -- [2] and
[3] -- and also because the build procedure can easily identify them in
`deb-local-build` and use the patched versions as expected by us (of
course, it they have been built previously).
The problem, however, is that although this image is currently being
built, there is a detail in it that can cause problems at run time.
Despite the build locating (and using) our patched packages, when it
searches for their dependencies, it always ends up using binaries from
repositories `deb-local-binary`, `deb-local-binary-containers` or
`deb-local-build`.
Which means that, if we have a dependency on
`deb-local-binary-openstack` meant for OpenStack Antelope, and the same
dependency on `deb-local-binary` meant for OpenStack Victoria, the image
build will use the latter, for the simple fact that it do not consider
the `openstack` layer (and, therefore, `deb-local-binary-openstack`).
To get around this problem, this change seeks to add a `sources.list`
for each build layer. By default, they are all disabled. However, if
necessary, they can be enabled and used in image builds based on Docker
or LOCI.
Note: This change is the prerequisite of [4].
The test plan with the `stx-openstackclients` image will be done
there.

Test Plan:
PASS - Build `stx-debian` base image
PASS - Build all container images with --clean and confirm that:
1. All container images were built successfully;
2. All container images were removed successfully.
