On 63f6dcdeb9 we added the support to
download either a .xz or a .zst tarball file. However, we missed adding
the code to properly unpack a .zst tarball file.

Docker containers support specifying the shm size using the --shm-size
option and support sandbox-level shm volumes, so we've added support for
shm volumes. Since Kubernetes doesn't support specifying the shm size,
it typically uses a memory-based emptydir as the container's shm, and
its size can be specified.

Since the rate limiter would be shared by cloud-hypervisor
and firecracker etc, thus move it from clh's config to
hypervisor config crate which would be shared by other vmm.

Given that Rust-based VMMs like cloud-hypervisor, Firecracker, and
Dragonball naturally offer user-level block I/O rate limiting, I/O
throttling has been implemented to leverage this capability for these
VMMs. This PR specifically introduces support for cloud-hypervisor.

Support for the share-rw=true parameter has been added. While this
parameter is essential for maintaining data consistency across multiple
QEMU instances sharing a backend disk image, its implementation also
serves to standardize parameters with the block device hotplug
functionality in kata-runtime/qemu.

Docker tests have been broken for a while and should be removed if we
cannot maintain those.
For now, though, let's limit it to run only with one hypervisor and
avoid wasting resources for no reason.

devmapper tests have been failing for a while. It's been breaking on the
kata-deploy deployment, which is most likely related to Disk Pressure.
Removing files was not enough to get the tests to run, so we'll just run
those with QEMU as a way to test fixes. Once we get the test working,
we can re-enable the other VMMs, but for now let's just not waste
resources for no reason.

The reason we're doing it here is because we've seen pods being evicted

I've hit this when using a machine with slow internet connection, which
took ages to download the kata-cleanup image, and then helm timed out in
the middle of the cleanup, leading to the cleanup job being restarted
and then bailing with an error as the runtimeclasses that kata-deploy
tries to delete were already deleted.

Since the cloud hypervisor's resize vCPU is an asynchronous operation,
it's possible that the previous resize operation hasn't completed when
the request is sent, causing the current call to return an error.
Therefore, several retries can be performed to avoid this error.

A minor release of QEMU is out, so update to it for fixes and features.
QEMU changelog: https://wiki.qemu.org/ChangeLog/10.1
Notes:
* AVX support is not an option to be enabled / disabled anymore.
* Passt requires Glibc 2.40.+, which means a dependency on Ubuntu 25.04
or newer, thus we're disabling it.

Experimental fw_cfg Device Support
This feature enables passing configuration data and files, such as VM
boot configurations (kernel, kernel cmdline, e820 memory map, and ACPI
tables), from the host to the guest. (#7117)
Experimental ivshmem Device Support
Support for inter-VM shared memory has been added. For more information,
please refer to the ivshmem documentation. (#6703)

Exclude 'cgroup' namespace from namespace checks during `allow_linux`
validation. This complements the existing exclusion of the 'network'
namespace.
As runtime-rs has specific cgroup namespace configurations, and excluding it from
policy validation ensures parity between runtime-rs and runtime-go implementations.
This allows focusing validation on critical namespaces like PID, IPC, and MNT, while
avoiding potential policy mismatches due to another cgroup namespace management by
the runtime-rs.
