The version mentioned in the `kata_config_version` needs to be
updated for any kernel config change or changed to the patches applied.
Without this, CI would not test with the latest kernel changes.
We use to enforce this earlier as part of CI when `packaging` was
a standalone repo.
Add back this check as part of a github action so that the check is
performed early on instead of a CI job.

Add cpu resize ability upon upcall communication channel. Runtime could
use ResizeVcpu VmmAction and pass the desired vCPU number to the
Dragonball hypervisor.
Dragonball will trigger the device manager service in guest kernel's
upcall server to do cpu resize.

The cmd.ExtraFiles feature that is used to implement appendFDs takes an
array of arbitray file descriptors and internally renumbers them to be
consecutive starting from 3, using dup2().
This isn't especially obvious : document it for the sake of clarity.

The QEMU log file is essentially about fine grain tracing of QEMU
internals and mostly useful for developpers, not production. Notably,
the log file isn't limited in size, nor rotated in any way. It means
that a container running in the VM could possibly flood the log file
with a guest triggerable trace. For example, on openshift, the log
file is supposed to reside on a per-VM 14 GiB tmpfs mount. This means
that each pod running with the kata runtime could potentially consume
this amount of host RAM which is not acceptable.
Error messages are best collected from QEMU's stderr as kata is doing
now since PR #5736 was merged. Drop support for the QEMU log file
because it doesn't bring any value but can certainly do harm.

LaunchQemu now connects a pipe to QEMU's stderr and makes it
usable by callers through a Go io.ReadCloser object. As
explained in [0], all messages should be read from the pipe
before calling cmd.Wait : introduce a LogAndWait helper to handle
that.
Fixes#5780

QEMU has always been started daemonized since the beginning. I
could not find any justification for that though, but it certainly
introduces a problem : QEMU stops logging errors when started this
way, which isn't accaptable from a support standpoint. The QEMU
community discourages the use of -daemonize ; mostly because
libvirt, QEMU's primary consummer, doesn't use this option and
prefers getting errors from QEMU's stderr through a pipe in order
to enforce rollover.
Now that virtcontainers knows how to start QEMU with a pre-
established QMP connection, let's start QEMU without -daemonize.
This requires to handle the reaping of QEMU when it terminates.
Since cmd.Wait() is blocking, call it from a goroutine.

LaunchCustomQemu() currently starts QEMU with cmd.Run() which is
supposed to block until the child process terminates. This assumes
that QEMU daemonizes itself, otherwise LaunchCustomQemu() would
block forever. The virtcontainers package indeed enables the
Daemonize knob in the configuration but having such an implicit
dependency on a supposedly configurable setting is ugly and fragile.
cmd.Run() is :
func (c *Cmd) Run() error {
if err := c.Start(); err != nil {
return err
}
return c.Wait()
}
Let's open-code this : govmm calls cmd.Start() and returns the
cmd to virtcontainers which calls cmd.Wait().
If QEMU doesn't start, e.g. missing binary, there won't be any
errors to collect from QEMU output. Just drop these lines in govmm.
Similarily there won't be any log file to read from in virtcontainers.
Drop that as well.

Running QEMU daemonized ensures that the QMP socket is ready to
accept connections when LaunchQemu() returns. In order to be
able to run QEMU undaemonized, let's handle that part upfront.
Create a listener socket and connect to it. Pass the listener
to QEMU and pass the connected socket to QMP : this ensures
that we cannot fail to establish QMP connection and that we
can detect if QEMU exits before accepting the connection.
This is basically what libvirt does.

QEMU's -qmp option can be passed the file descriptor of a socket that
is already in listening mode. This is done with by passing `fd=XXX`
to `-qmp` instead of a path. Note that these two options are mutually
exclusive : QEMU errors out if both are passed, so we check that as
well in the validation function.
While here add the `path=` stanza in the path based case for clarity.

When QEMU is launched daemonized, we have the guarantee that the
QMP socket is available. In order to launch a non-daemonized QEMU,
the QMP connection should be created before QEMU is started in order
to avoid a race. Introduce a variant of QMPStart() that can use such
an existing connection.

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.
