Debian: Add build structure for virt/libvirt

Browse Source 
This change adds the necessary files for the libvirt package to be built
for Debian.
This change is the new approach for porting this package and will be
replacing an old change that will no longer be valid [1].

All the libvirt related packages (rpm) delivered on CentOS builds of
starlingx were verified to exist or have an equivalent package for the
Debian Bullseye (deb) distro [2], which is based on libvirt 7.0.0.

The upstream Debian packaging, patches and configuration will be used as
is, although the deb_patches directory will contain a patch to add few
starlingx specific files that are required, based on how stx-libvirt [3]
was previously built and delivered to CentOS.
This change will deprecate the starlingx-staging/stx-libvirt repository
and any future starlingx change to libvirt will now be placed here,
on top of debian/7.0.0-3 (bullseye) version.

Earlier (on CentOS) the base point was the libvirt 4.7.0 release and 17
starlingx specific commits were added to deliver new features or fix
bugs. Now, the base point will be the libvirt 7.0.0 release package
already prepared for Debian [4] and those 17 commits port will be
evaluated and done, in case they are still needed.

The patches dir will contain source code patches required for
stx-libvirt, that is, the code that was earlier added on top of 4.7.0
libvirt release to add StarlingX required functionalities.
The work done on this change is simply porting the code changes,
copying it and doing the minimum required updates when it is needed.
If more than one commit (from that list) can be placed on a single
patch, the patch description will contain all the necessary references.

The list of commits follow, where the "-" character indicates that the
commit was dropped now that we are based on 7.0.0:
-8c46e4 conf: Introduce VIR_DEFINE_AUTOPTR_FUNC for virStorageVolDef
-e8c2ae storage: add support for new rbd_list2 method
-dee98c storage: split off code for calling rbd_list

Test Plan:
PASS: Build the libvirt packages
PASS: Build Debian ISO with libvirt packages
PASS: Bootstrap Debian ISO on AIO-SX
PASS: Ensure libvirt packages are installed (apt list --installed)
PASS: Lock/Unlock AIO-SX *
* Future tests regarding the libvirt/qemu runtime features will be done
once all the pieces are in place in the ISO.

Subject: [PATCH] STX: Customize Debian build files
Adds to libvirt Debian build instructions, starlingx specific files
based on how starlingx-staging/stx-libvirt was previously built and
delivered on CentOS, adding to the following:
* Enabling syslog for libvirtd
* Setting "auth_tcp" to "none"
* Logrotate files
* Qemu hook

Subject: [PATCH] STX: Stop processing memory stats if balloon fails
We were seeing deadlock on the second query because the VM
had already been destroyed. In that case, the first query
fails but unfortunately we ignore the return code and charge
ahead anyway and do the second query which then hangs. We
now respect the return code if it indicates failure on the
first query.

Subject: [PATCH] STX: Increase timeout for connecting to monitor
When launching a large number of VMs concurrently on a
single host, eg. 10, it can take a while
for them to zero memory and attach to the monitor. After
measuring many such delays in this concurrent launch
stress test, we conclude that an extra minute
of waiting should suffice.
