Nydus+guest_pull has specific behavior where it improperly handles image layers on
the host, causing the CRI to not find /etc/passwd and /etc/group files
on container images which have them. The unfortunately causes different
outcomes w.r.t. GID used which we are trying to enforce with policy.
This behavior is observed/explained in https://github.com/kata-containers/kata-containers/issues/11162
Handle this exception with a config.settings.cluster_config.guest_pull
field. When this is true, simply ignore the /etc/* files in the
container image as they will not be parsed by the CRI.

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.
Redis is an interesting container image to test with because it includes
a /etc/passwd file with existing user/group configuration of 1000:1000 baked in.

It's used an AKS managed ingress controller which keeps two nginx pod
replicas where both request 500m of CPU. On small VMs like we've used on
CI for running the CoCo non-TEE tests, it left only a few amount of CPU
for the tests. Actually, one of these pod replicas won't even get
started. So let's patch the ingress controller to have only one replica
of nginx.

The Azure AKS addon-http-application-routing add-on is deprecated and
cannot be enabled on new clusters which has caused some CI jobs to fail.
Migrated our code to use approuting instead. Unlike
addon-http-application-routing, this add-on doesn't
configure a managed cluster DNS zone, but the created ingress has a
public IP. To avoid having to deal with DNS setup, we will be using that
address from now on. Thus, some functions no longer used are deleted.

genpolicy is sending more HTTPS requests than other components during
CI so it's more likely to be affected by transient network errors
similar to:
ConnectError(
"dns error",
Custom {
kind: Uncategorized,
error: "failed to lookup address information: Try again",
},
)
Note that genpolicy is not the only component hitting network errors
during CI. Recent example from a different component:
"Message: failed to create containerd task: failed to create shim task:
failed to async pull blob stream HTTP status server error (502 Bad Gateway)"
This CI change might help just with the genpolicy errors.

This test we will test initdata in the following logic
1. Enable image signature verification via kernel commandline
2. Set Trustee address via initdata
3. Pull an image from a banned registry
4. Check if the pulling fails with log `image security validation
failed` the initdata works.
Note that if initdata does not work, the pod still fails to launch. But
the error information is `[CDH] [ERROR]: Get Resource failed` which
internally means that the KBS URL has not been set correctly.

While working on #10559, I realized that some parts of the codebase use
$GH_PR_NUMBER, while other parts use $PR_NUMBER.
Notably, in that PR, since I used $GH_PR_NUMBER for CoCo non-TEE tests
without realizing that TEE tests use $PR_NUMBER, the tests on that PR
fail on TEEs:
https://github.com/kata-containers/kata-containers/actions/runs/12818127344/job/35744760351?pr=10559#step:10:45
...
44 error: error parsing STDIN: error converting YAML to JSON: yaml: line 90: mapping values are not allowed in this context
...
135 image: ghcr.io/kata-containers/csi-kata-directvolume:

So let's unify on $GH_PR_NUMBER so that this issue doesn't repro in the
future: I replaced all instances of PR_NUMBER with GH_PR_NUMBER.
Note that since some test scripts also refer to that variable, the CI
for this PR will fail (would have also happened with the converse
substitution), hence I'm not adding the ok-to-test label and we should
force-merge this after review.

On s390x, some tests for trusted storage occasionally failed due to:
```bash
etcdserver: request timed out
```
or
```bash
Internal error occurred: resource quota evaluation timed out
```
These timeouts were not observed previously on k3s but occur
sporadically on kubeadm. Importantly, they appear to be temporary
and transient, which means they can be ignored in most cases.
To address this, we introduced a new wrapper function, `retry_kubectl_apply()`,
for `kubectl create`. This function retries applying a given manifest up to 5
times if it fails due to a timeout. However, it will still catch and handle
any other errors during pod creation.
