- D-Bus enabling now occurs only in setup_rootfs (instead of
prepare_overlay and setup_rootfs)
- Adjust permissions of / so dbus-broker will be able to traverse FS
These changes enables kata-agent to successfully communicate with D-Bus.

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.

When starting an initrd the kernel expects to find /dev/console in the initrd,
so that it can connect it as stdin/stdout/stderr to the /init process. If the
device node is missing the kernel will complain that it was unable to open an
initial console. If kata-agent is the initrd init process, it will also result
in log messages not being logged to console and thus not forwarded to host
syslog.
Add a set of standard device nodes for completeness, so that console logging
works. To do that we install the makedev packge which provides a MAKEDEV helper
that knows the major/minor numbers. Unfortunately the debian package tries to
create devnodes from postinst, which can be suppressed if systemd-detect-virt
is present. That's why we create a small dummy script that matches what
systemd-detect-virt would output (anything is enough to suppress mknod).

As QEMU released its v7.2.0 version in December last year, last do the
bump on our side.
A few configuration options have been removed between the v6.2.0 (the
version we currently use) and v7.2.0, so those have also been dropped
from our configure-hypervison.sh script (for this specific version).
Also, we're explicitly setting --disable-virtiofsd for the platforms
that we're testing using the rust version.

In order to let upcall being used by Kata Container, we need to add
those patches into kernel build script.
Currently, only when experimental (-e) and hypervisor type dragonball
(-t dragonball) are both enabled, that the upcall patches will be
applied to build a 5.10 guest kernel.

Upcall is a direct communication tool between VMM and guest developed
upon vsock. The server side of the upcall is a driver in guest kernel
(kernel patches are needed for this feature) and it'll start to serve
the requests after the kernel starts. And the client side is in
Dragonball VMM , it'll be a thread that communicates with vsock through
uds.
We want to keep the lightweight of the VM through the implementation of
the upcall, through which we could achieve vCPU hotplug, virtio-mmio
hotplug without implementing complex and heavy virtualization features
such as ACPI virtualization.

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.
