stx-openstack: libvirt failling on Debian

[Thales Elero Cervi]

Brief Description
-----------------
The initial tests of stx-openstack on Debian, using the stx-libvirt image based on stx-debian failed. The libvirt pod fails to spawn (CrashLoopBackOff) and breaks the application apply process.

Severity
--------
Critical: stx-openstack can not be applied.

Steps to Reproduce
------------------
* Upload stx-openstack (Debian stx)
* Helm-override libvirt image to use a custom built stx-libvirt
* Apply stx-openstack

Expected Behavior
------------------
stx-openstack should apply successfully

Actual Behavior
----------------
stx-openstack apply fails

Reproducibility
---------------
Reproducible

System Configuration

    Add stx-libvirt build dependencies

    This change adds the packages required to be installed on our delivered
    stx-libvirt image. Therefore, when building the Docker image we can
    download these dependencies from our local repository.

    Test Plan:
    PASS - Run downloader -b -s
    PASS - Build stx-libvirt image

    Port stx-libvirt base image to stx-debian

    This change enables building the stx-libvirt Docker image within the
    Debian build framework. It is now based on stx-debian and
    following the new convention for StarlingX images.

    Test Plan:
    PASS - Build libvirt debian package
    PASS - Build stx-libvirt image
    PASS - Manually upload built image to a system, use helm-override to
           change the libvirt container image and apply stx-openstack
    PASS - Ensure the libvirt Pod successfully starts and is running
    PASS - Ensure libvirt Pod Liveness and Readiness probes are healthy
