Currently, when a new sandbox resource controller is created with cgroupsv2 and sandbox_cgroup_only is disabled,
the cgroup management falls back to cgroupfs. During deletion, `IsSystemdCgroup` checks if the path contains `:`
and tries to delete the cgroup via systemd. However, the cgroup was originally set up via cgroupfs and this process
fails with `lstat /sys/fs/cgroup/kubepods.slice/kubepods-besteffort.slice/....scope: no such file or directory`.
This patch updates the deletion logic to take in to account the sandbox_cgroup_only=false option and in this case uses
the cgroupfs delete.

This enables guest pull via config, without the need of any external
snapshotter. When the config enables runtime.experimental_force_guest_pull, instead of
relying on annotations to select the way to share the root FS, we always
use guest pull.

for confidential guests is not necessary as the RNG source cannot
be trusted and the guest kernel has the driver already disable as well.

We've been using the

to get cri-o annotations, which has some major CVEs in, but
in v5 most of the annotations were moved into crio (from 1.30)
(see https://github.com/cri-o/cri-o/pull/7867). Let's switch
to use the cri-o annotations module instead and remediate

Some cni plugins will set the MTU of some routes, such as cilium will
modify the MTU of the default route. If the mtu of the route is not set
correctly, it may cause excessive fragmentation or even packet loss of
network packets. Therefore, this PR adds the setting of the MTU of the
route. First, when obtaining the route, if the MTU is set, the MTU will
also be obtained and set to the route in the guest.

We're bringing to *Cloud Hypervisor only* the reclaim_guest_freed_memory
option already present in the runtime-rs.
This allows us to use virtio-balloon for the hypervisor to reclaim
memory freed by the guest.
The reason we're not touching other hypervisors is because we're very
much aware of avoiding to clutter the go code at this point, so we'll
leave it for whoever really needs this on other hypervisor (and trust
me, we really do need it for Cloud Hypervisor right now ;-)).

io.katacontainers.config.runtime.cc_init_data specifies initdata used by
the pod in base64(gzip(initdata toml)) format. The initdata will be
encapsulated into an initdata image and mount it as a raw block device
to the guest.
The initdata image will be aligned with 512 bytes, which is chosen as a
usual sector size supported by different hypervisors like qemu, clh and
dragonball.
Note that this patch only adds support for qemu hypervisor.

For a use case, we want to set the SNP IDBlock, which allows
configuring the AMD ASP to enforce parameters like expected launch
digest at launch. The struct with the config that should be enforced
(IDBlock) is signed. The public key is placed in the auth block and
the signature is verified by the ASP before launch. The digest of the
public key is also part of the attestation report (ID_KEY_DIGESTS).

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.
