Introduce new test case in k8s-iptables.bats which verifies that
workloads can configure iptables in the UVM.
Users discovered that they weren't able to do this for common usecases
such as istio. Proper support for this should be built into UVM
kernels. This test ensures that current and future kernel
configurations don't regress this functionality.

Currently, the UVM kernel fails for istio deployments (at least with the
version we tested, 1.27.0). This is because the istio sidecar container
uses ip6tables and the required kernel configs are not built-in:
```
iptables binary ip6tables has no loaded kernel support and cannot be used, err: exit status 3 out: ip6tables v1.8.10 (legacy):
can't initialize ip6tables table `filter': Table does not exist (do you need to insmod?)
Perhaps ip6tables or your kernel needs to be upgraded.
```

In k8s-guest-pull-image.bats, `failed to pull image` is
not caught by assert_logs_contain() for runtime-rs.
To ensure consistency, this commit changes `failed` to
`Failed`, which works for both runtimes.

Mount validation for sealed secret requires the base path to start with
`/run/kata-containers/shared/containers`. Previously, it used
`/run/kata-containers/sandbox/passthrough`, which caused test
failures where volume mounts are used.
This commit renames the path to satisfy the validation check.

ef642fe890 added a special case to avoid
moving cgroups that are on the "default" slice in case of deletion.
However, this special check should be done in the Parent() method
instead, which ensures that the default resource controller ID is
returned, instead of ".".

We moved to `.zst`, but users still use the upstream kata-manager to

Similar to what we've done for Cloud Hypervisor in the commit
9f76467cb7, we're backporting a runtime-rs
feature that would be benificial to have as part of the go runtime.
This allows users to use virito-balloon for the hypervisor to reclaim
memory freed by the guest.

Although the compress ratio is not as optimal as using xz, it's way
faster to compress / uncompress, and it's "good enough".
This change is not small, but it's still self-contained, and has to get

The default `reconnect_timeout` (3 seconds) was found to be insufficient for
IBM SEL when using VSOCK. This commit updates the timeouts as follows:
- `dial_timeout_ms`: Set to 90ms to match the value used in go-runtime for IBM SEL
- `reconnect_timeout_ms`: Increased to 5000ms based on empirical testing

Add support for the `InitData` resource config on IBM SEL,
so that a corresponding block device is created and the
initdata is passed to the guest through this device.
Note that we skip passing the initdata hash via QEMU’s
object, since the hypervisor does not yet support this
mechanism for IBM SEL. It will be introduced separately
once QEMU adds the feature.

Linux v6.16 brings some useful features for the confidential guests.
Most importantly, it adds an ABI to extend runtime measurement registers
(RTMR) for the TEE platforms supporting it. This is currently enabled
on Intel TDX only.
The kernel version bump from v6.12.x to v6.16 forces some CONFIG_*
changes too:
MEMORY_HOTPLUG_DEFAULT_ONLINE was dropped in favor of more config
choices. The equivalent option is MHP_DEFAULT_ONLINE_TYPE_ONLINE_AUTO.
X86_5LEVEL was made unconditional. Since this was only a TDX
configuration, dropping it completely as part of v6.16 is fine.
CRYPTO_NULL2 was merged with CRYPTO_NULL. This was only added in
confidential guest fragments (cryptsetup) so we can drop it in this update.
CRYPTO_FIPS now depends on CRYPTO_SELFTESTS which further depends on
EXPERT which we don't have. Enable both in a separate config fragment
for confidential guests. This can be moved to a common setting once
other targets bump to post v6.16.
CRYPTO_SHA256_SSE3 arch optimizations were reworked and are now enabled
by default. Instead of adding it to whitelist.conf, just drop it completely
since it was only enabled as part of "measured boot" feature for
confidential guests. CONFIG_CRYPTO_CRC32_S390 was reworked the same way.
In this case, whitelist.conf is needed.
