To support virtio-net-ccw for s390x, add CCW devices to the Endpoint
interface. Add respective fields and functions to implementing structs.
Device paths may be empty. PciPath resolves this by being a list that
may be empty, but this design does not map to CcwDevice. Use a pointer
instead.

Adding devices by CDI annotation can fail for a variety of reasons. If
that happens, it's helpful to know the root cause of the issue (CDI spec
missing, malformatted, requested device not present, etc.).
This commit adds the root cause of the CDI device addition to the errors
reported back to the caller. Since this error is bubbled up all the way
back to the shimv2 task.Create handler, it will be visible in Kubernetes
logs and enable fixing the root cause.

This commit introduces a new gRPC device type, `vfio-ap-cold`, to support
VFIO-AP coldplug. This enables the VM guest to handle passthrough devices
differently from VFIO-AP hotplug.
With this new type, the guest no longer needs to wait for events (e.g., device
addition) because the device already exists at the time the device type is checked.

Even though ociSpec.Linux.Devices is preserved when vfio_mode is VFIO,
it has not been updated correctly for coldplug scenarios. This happens
because the device info passed to the agent via CreateContainerRequest
is dropped by the Kata runtime.
This commit ensures that the device info is added to the sandbox's
device manager when vfio_mode is VFIO and coldPlugVFIO is true
(e.g., vfio-ap-cold), allowing ociSpec.Linux.Devices to be properly
updated with the device information before the container is created on
the guest.

This commit sets memory config `shared` to false in cloud hypervisor
when creating vm with shared_fs=None && hugePages = false.
Currently in runtime/virtcontainers/clh.go,the memory config shared is by default set to true.
As per the CLH memory document,
(a) shared=true is needed in case like when using virtio_fs since virtiofs daemon runs as separate process than clh.
(b) for shared_fs=none + hugespages=false, shared=false can be set to use private anonymous memory for guest (with no file backing).
(c) Another memory config thp (use transparent huge pages) is always enabled by default.
As per documentation, (b) + (c) can be used in combination.
However, with the current CLH implementation, the above combination cannot be used since shared=true is always set.

Method StopVM could kill shim process together with VM pieces.
Signed-off-by: Konstantin Khlebnikov <koct9i@gmail.com>
When QEMU is terminated by signal 15, it deletes the PidFile.
Upon detecting that QEMU has exited, the shim executes the stopVM function.
If the PidFile is not found, the PID is set to 0.
Subsequently, the shim executes `kill -9 0`, which terminates the current process group.
This prevents any further logic from being executed, resulting in resources not being cleaned up.

PhysicalEndpoint unbinds its VF interface and rebinds it as a VFIO device,
then cold-plugs the VFIO device into the guest kernel.
When `cold_plug_vfio` is set to "no-port", cold-plugging the VFIO device
will fail.
This change checks if `cold_plug_vfio` is enabled before creating PhysicalEndpoint
to avoid unnecessary VFIO rebind operations.

Our code for handling images being pulled inside the guest relies on a
containerType ("sandbox" or "container") being set as part of the
container annotations, which is done by the CRI Engine being used, and
depending on the used CRI Engine we check for a specfic annotation
related to the image-name, which is then passed to the agent.
However, when running kata-containers without kubernetes, specifically
when using `nerdctl`, none of those annotations are set at all.
One thing that we can do to allow folks to use `nerdctl`, however, is to
take advantage of the `--label` flag, and document on our side that
users must pass `io.kubernetes.cri.image-name=$image_name` as part of
the label.
By doing this, and changing our "fallback" so we can always look for
such annotation, we ensure that nerdctl will work when using the nydus
snapshotter, with kata-containers, to perform image pulling inside the
pod sandbox / guest.

The current implementation for device binding using driver bind/unbind
and new_id fails in the scenario when the physical device is not bound
to a driver before assigning it to vfio.
There exists and updated mechanism to accomplish the same that does not
have the same issue as above.
The driver_override field for a device allows us to specify the driver for a device
rather than relying on the bound driver to provide a positive match of the
device. It also has other advantages referenced here:
https://patchwork.kernel.org/project/linux-pci/patch/1396372540.476.160.camel@ul30vt.home/
So use the updated driver_override mechanism for binding/unbinding a
physical device/virtual function to vfio-pci.
