The add_allow_all_policy_to_yaml in tests_common.sh needs some
improvements so that this function can support pod manifests with
different resource kinds. For now, moving the Secret definition

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.

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.)

This change crystallizes and simplifies the current handling of /dev
hostPath mounts with virtually no functional change.
Before this change:
- If a mount DESTINATION is in /dev and it is a non-regular file on the HOST,
the shim passes the OCI bind mount as is to the guest (e.g.
/dev/kmsg:/dev/kmsg). The container rightfully sees the GUEST device.
- If the mount DESTINATION does not exist on the host, the shim relies on
k8s/containerd to automatically create a directory (ie. non-regular file) on
the HOST. The shim then also passes the OCI bind mount as is to the guest. The
container rightfully sees the GUEST device.
- For other /dev mounts, the shim passes the device major/minor to the guest
over virtio-fs. The container rightfully sees the GUEST device.
After this change:
- If a mount SOURCE is in /dev and it is a non-regular file on the HOST,
the shim passes the OCI bind mount as is to the guest. The container
rightfully sees the GUEST device.
- The shim does not anymore rely on k8s/containerd to create missing mount
directories. Instead it explicitely handles missing mount SOURCES, and
treats them like the previous bullet point.
- The shim no longer uses virtio-fs to pass /dev device major/minor to the
guest, instead it passes the OCI bind mount as is.

We recently hit the following error during build:
```
RUN ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key -P ""
OpenSSL version mismatch. Built against 3050003f, you have 30500010
```
This happened because `alpine:latest` moved forward and the `ssh-keygen`
binary in the base image was compiled against a newer OpenSSL version
that is not available at runtime.
Pinning the base image to the stable release (3.20) avoids the mismatch
and ensures consistent builds.

Introduce new test case in k8s-iptables.bats which verifies that
workloads can configure iptables in the UVM.

configurations don't regress this functionality.

The actual memory usage on the host is equal to the hypervisor memory usage
plus the user memory usage. An OOM killer might kill the shim when the
memory limit on host is same with that of container and the container
consumes all available memory. In this case, the containerd will never
receive OOM event, but get "task exit" event. That makes the `k8s-oom.bats`
test fail.
The fix is to add a new container to increase the sandbox memory limit.
When the container "oom-test" is killed by OOM killer, there is still
available memory for the shim, so it will not be killed.

This patch updates the container image for the CI test workloads:
- `k8s-layered-sc-deployment.yaml`
- `k8s-pod-sc-deployment.yaml`
- `k8s-pod-sc-nobodyupdate-deployment.yaml`
- `k8s-pod-sc-supplementalgroups-deployment.yaml`
- `k8s-policy-deployment.yaml`
Also updates unit tests:
- `test_create_container_security_context`
- `test_create_container_security_context_supplemental_groups`
This fixes tests failing due to an image pull error as the previous image is no longer available in
the container registry.

Introduce tests to check for policy correctness on a redis deployment
with 1. a pod-level securityContext 2. a container-level securityContext
which shadows the pod-level securityContext 3. a pod-level
securityContext which selects an existing user (nobody), causing a new GID to be selected.

The nginx container seems to error out when using UID=123.
Depending on the timing between container initialization and "kubectl
wait", the test might have gotten lucky and found the pod briefly in
Ready state before nginx errored out. But on some of the nodes, the pod
never got reported as Ready.
Also, don't block in "kubectl wait --for=condition=Ready" when wrapping
that command in a waitForProcess call, because waitForProcess is
designed for short-lived commands.
