Create a guest image to support SELinux for containers inside the guest
if `SELINUX=yes` is specified. This works only if the guest rootfs is
CentOS and the init service is systemd, not the agent init. To enable
labeling the guest image on the host, selinuxfs must be mounted on the
host. The kata-agent will be labeled as `container_runtime_exec_t` type.

CONFIG_X86_SGX is introduced after kernel 5.11, and that config is a
default x86_64 config for Kata build-kernel.sh script.
But if we use -v to specify any kernel version below 5.11 will cause an
inevitable error because CONFIG_X86_SGX is not supported in older
kernels and that may cause problem for the situation if we need kernel
version below 5.11.
So I propose to put CONFIG_X86_SGX into whitelist.conf to avoid break
building guest kernel below 5.11.

The compile option link-self-contained=yes asks rustc to use
C library startup object files that come with the compiler,
which are not available on the target s390x-unknown-linux-gnu.
A build does not contain any startup files leading to a
broken executable entry point (causing segmentation fault).

1. Implemented a rust module for operating cgroups through systemd with the help of zbus (src/agent/rustjail/src/cgroups/systemd).
2. Add support for optional cgroup configuration through fs and systemd at agent (src/agent/rustjail/src/container.rs).
3. Described the usage and supported properties of the agent systemd cgroup (docs/design/agent-systemd-cgroup.md).

Differently than every single other bit that's part of our repo, QEMU
has been using a single Dockerfile that prepares an environment where
the project can be built, but *also* building the project as part of
that very same Dockerfile.
This is a problem, for several different reasons, including:
* It's very hard to have a reproducible build if you don't have an
archived image of the builder
* One cannot cache / ipload the image of the builder, as that contains
already a specific version of QEMU
* Every single CI run we end up building the builder image, which
includes building dependencies (such as liburing)
Let's split the logic into a new build script, and pass the build script
to be executed inside the builder image, which will be only responsible
for providing an environment where QEMU can be built.

When moving to building the CI artefacts using the kata-deploy scripts,
we've noticed that the build would fail on any machine where the tarball
wasn't officially provided.
This happens as rust is missing from the 1st layer container. However,
it's a very common practice to leave the 1st layer container with the
minimum possible dependencies and install whatever is needed for
building a specific component in a 2nd layer container, which virtiofsd
never had.
In this commit we introduce the second layer containers (yes,
comtainers), one for building virtiofsd using musl, and one for building
virtiofsd using glibc. The reason for taking this approach was to
actually simplify the scripts and avoid building the dependencies
(libseccomp, libcap-ng) using musl libc.

The previously used repo will be removed by Intel, as done with the one
used for TDX kernel. The TDX team has already worked on providing the
patches that were hosted atop of the QEMU commit with the following hash
4c127fdbe81d66e7cafed90908d0fd1f6f2a6cd0 as a tarball in the
https://github.com/intel/tdx-tools repo, see
https://github.com/intel/tdx-tools/pull/162.
On the Kata Containers side, in order to simplify the process and to
avoid adding hundreds of patches to our repo, we've revived the
https://github.com/kata-containers/qemu repo, and created a branch and a
tag with those hundreds of patches atop of the QEMU commit hash
4c127fdbe81d66e7cafed90908d0fd1f6f2a6cd0. The branch is called
4c127fdbe81d66e7cafed90908d0fd1f6f2a6cd0-plus-TDX-v3.1 and the tag is
called TDX-v3.1.
Knowing the whole background, let's switch the repo we're getting the
TDX QEMU from.

The previously used repo has been removed by Intel. As this happened,

On the Kata Containers side, in order to simplify the process and to

a tag with those ~1400 patches atop of the v5.15. The branch is called
v5.15-plus-TDX, and the tag is called 5.15-plus-TDX (in order to avoid
having to change how the kernel builder script deals with versioning).
Knowing the whole background, let's switch the repo we're getting the

In order to ensure that the proxy configuration is passed to the 2nd
layer container, let's ensure the $HOME/.docker/config.json file is
exposed inside the 1st layer container.
For some reason which I still don't fully understand exporting
https_proxy / http_proxy / no_proxy was not enough to get those
variables exported to the 2nd layer container.
In this commit we're creating a "$HOME/.docker" directory, and removing
it after the build, in case it doesn't exist yet. The reason we do this
is to avoid docker not running in case "$HOME/.docker" doesn't exist.
This was not tested with podman, but if there's an issue with podman,
the issue was already there beforehand and should be treated as a
different problem than the one addressed in this commit.

Shell expands `*"rc"*` to the top-level `src` directory. This results
in comparing a version with a directory name. This doesn't make sense
and causes the script to choose the wrong branch of the `if`.
The intent of the check is actually to detect `rc` in the version.

kata-deploy files must be adapted to a new release. The cases where it
happens are when the release goes from -> to:
* main -> stable:
* kata-deploy-stable / kata-cleanup-stable: are removed
* stable -> stable:
* kata-deploy / kata-cleanup: bump the release to the new one.
There are no changes when doing an alpha release, as the files on the
"main" branch always point to the "latest" and "stable" tags.

In the commit 54d6d01754 we ended up
removing the BUILD_SUFFIX argument passed to QEMU as it only seemed to
be used to generate the HYPERVISOR_NAME and PKGVERSION, which were added
as arguments to the dockerfile.
However, it turns out BUILD_SUFFIX is used by the `qemu-build-post.sh`
script, so it can rename the QEMU binary accordingly.
Let's just bring it back.
