The test case designed to verify policy failures due to an "unexpected
capability" was misconfigured. It was using "CAP_SYS_CHROOT" as the
unexpected capability to be added.
This configuration was flawed for two main reasons:
1.Incorrect Syntax: Kubernetes Pod specs expect capability names without
the "CAP_" prefix (e.g., "SYS_CHROOT", not "CAP_SYS_CHROOT").
This made the test case's premise incorrect from a K8s API perspective.
2.Part of Default Set: "SYS_CHROOT" is already included in the
`default_caps` list for a standard container. Therefore, adding it would
not trigger a policy violation, defeating the purpose of the
"unexpected capability" test.
Furthermore, a related issue was observed where a malformed capability
like "CAP_CAP_SYS_CHROOT" was being generated, causing parsing failures
in the `oci-spec-rs` library. This was a symptom of incorrect string
manipulation when handling capabilities.
This commit corrects the test by selecting "SYS_NICE" as the unexpected
capability. "SYS_NICE" is a more suitable choice because:
- It is a valid Linux capability.
- It is relatively harmless.
- It is **not** part of the default capability set defined in
`genpolicy-settings.json`.
By using "SYS_NICE", the test now accurately simulates a scenario where
a Pod requests a legitimate but non-default capability, which the policy
(generated from a baseline Pod without this capability) should correctly
reject. This change fixes the test's logic and also resolves the
downstream `oci-spec-rs` parsing error by ensuring only valid capability
names are processed.

There are several changes needed in order to get this test working with
CC, and yet we still are skipping it.
Basically, we need to:
* Pull an authenticated image inside the guest, which requires:
* Using Trustee to release the credential
* We still depend on a PR to be merged on Trustee side
* https://github.com/confidential-containers/trustee/pull/1035
* We still depend on a Trustee bump (including the PR above) on our
side
Apart from those changes, I ended up "duplicating" the tests by adding a
"-tee" version of those, which already have:
* The proper kbs annotations set up
* Dropped host mounts
* Increases the memory needed
Last but not least, as "bats" probably means "being a terrible script",
I had to re-arrange a few things otherwise the tests would not even run
due to bats-isms that I am sincerely not able to pin-point.

We added the tests using virtio-9p as we knew it'd require incremental
changes to be able to use any kind of guest-pull method.
Now, as in the coming commits we'll be actually ensuring that guest-pull
works and is in use, we can enforce the experimental_force_guest_pull
usage for the nvidia cases.
Note: We're using experimental_force_guest_pull instead of
nydus-snapshotter due to stability concerns with the snapshotter.

The new image reference has changed to mcr.microsoft.com/oss/v2/kubernetes/pause:3.6
from mcr.microsoft.com/oss/kubernetes/pause:3.6.
The new image uses by default UID=0, GID=0 while the older. The older image had:
UID=65535, GID=65535.
There is a new pause_container_id_policy field in genpolicy-settings.json, informing
genpolicy about the way AdditionalGids gets updated - "v1" for the older behavior
and "v2" for the newer AKS version:
- When using v1, the default value of AdditionalGids is {65535}.
- When using v2, the default value of AdditionalGids is {}.
UID=65535 and GID=65535 are still hard-coded by default in genpolicy-settings.json.
We might be able to remove/ignore these fields in the future, if we'll stop relying
on policy::KataSpec::get_process_fields to use these fields.
A new CI function adapt_common_policy_settings_for_aks() changes the pause container
UID, GID, pause_container_id_policy, and image ref settings values when testing on
AKS Hosts - i.e., when testing coco-dev or mariner Hosts.
The genpolicy workarounds for the unexpected behavior with guest pull enabled have
been improved to use the current container's GID instead of hard-coding GID=0 as the
guest pull default. Also, AdditionalGids gets updated when the current container's GID is
changing, instead of always changing the AdditionalGids at the very end of
policy::AgentPolicy::get_container_process(), when the relevant evolution of the GID
value was no longer available.

While the primary goal of this change is to detect regressions to the
NVIDIA SNP GPU scenario, various improvements to reflect a more
realistic CC setting are planned in subsequent changes, such as:
* moving away from the overlayfs snapshotter
* disabling filesystem sharing
* applying a pod security policy
* activating the GPUs only after attestation
* using a refined approach for GPU cold-plugging without requiring
annotations
* revisiting pod timeout and overhead parameters (the podOverhead value
was increased due to CUDA vectorAdd requiring about 6Gi of
podOverhead, as well as the inference and embedqa requiring at least
12Gi, respectively, 14Gi of podOverhead to run without invoking the
host's oom-killer. We will revisit this aspect after addressing
points 1. and 2.)

We have 2 tests running on GitHub provided runners:
* devmapper
* CRI-O
- devmapper situation
For devmapper, we're currently testing devmapper with s390x as part of
one of its jobs.
More than that, this test has been failing here due to a lack of space
in the machine for quite some time, and no-action was taken to bring it
back either via GARM or some other way.
With that said, let's rely on the s390x CI to test devmapper and avoid
one extra failure on our CI by removing this one.
- cri-o situation
CRI-O is being tested with a fixed version of kubernetes that's already
reached its EOL, and a CRI-O version that matches that k8s version.
There has been attempts to raise issues, and also to provide a PR that
does at least part of the work ... leaving the debugging part for the
maintainers of the CI. However, there was no action on those from the
maintainers.

If a ConfigMap has more than 8 files it will not be mounted watchable
[1]. However, genpolicy assumes that ConfigMaps are always mounted at a
watchable path, so containers with large ConfigMap mounts fail
verification.
This commit allows mounting ConfigMaps from watchable and non-watchable
directories. ConfigMap mounts can't be meaningfully verified anyway, so
the exact location of the data does not matter, except that we stay in
the sandbox data dirs.
