Generate policy that validates each exec command line argument, instead
of joining those args and validating the resulting string. Joining the
args ignored the fact that some of the args might include space
characters.
The older format from genpolicy-settings.json was similar to:
"ExecProcessRequest": {
"commands": [
"sh -c cat /proc/self/status"
],
"regex": []
},
That format will not be supported anymore. genpolicy will detect if its
users are trying to use the older "commands" field and will exit with
a relevant error message in that case.
The new settings format is:
"ExecProcessRequest": {
"allowed_commands": [
[
"sh",
"-c",
"cat /proc/self/status"
]
],
"regex": []
},

Currently, we have found that `assert_logs_contain` does not work on TDX.
We manually located the specific log, but it fails to get the log using `kubectl debug`. The error found in CI is:
```
warning: couldn't attach to pod/node-debugger-984fee00bd70.jf.intel.com-pdgsj,
falling back to streaming logs: error stream protocol error: unknown error
```
Upon debugging the TDX CI machine, we found an error in containerd:
```
Attach container from runtime service failed" err="rpc error: code = InvalidArgument desc = tty and stderr cannot both be true"
containerID="abc8c7a546c5fede4aae53a6ff2f4382ff35da331bfc5fd3843b0c8b231728bf"
```
We believe this is the root cause of the test failures in TDX CI.
Therefore, we need to ensure that tty and stderr are not set to true at same time.

It is not good practice to call repack_secure_image() from a bats file
because the test code might not consider cases where `qemu-se` is used
as `KATA_HYPERVISOR`.
This commit moves the function call to set_metadata_annotation() if a key
includes `kernel_params` and `KATA_HYPERVISOR` is set to `qemu-se`, allowing
developers to focus on the test scenario itself.

Add policy to pod-secret-env.yaml from k8s-credentials-secrets.bats.
Policy was already auto-generated for the other pod used by the same
test (pod-secret.yaml). pod-secret-env.yaml was inconsistent,
because it was taking advantage of the "allow all" policy built into
the Guest image. Sooner or later, CI Guests for CoCo will not get the
"allow all" policy built in anymore and pod-secret-env.yaml would
have stopped working then.
Note that pod-secret-env.yaml continues to use an "allow all" policy
after these changes. #10033 must be solved before a more restrictive
policy will be generated for pod-secret-env.yaml.

Since #9904 was merged, newly introduced tests for `k8s-guest-pull-image-authenticated.bats`
have been failing on IBM SE (s390x). The agent fails to start because a kernel parameter
cannot pass to the guest VM via annotation. To fix this, the boot image must be rebuilt with
updated parameters.
This commit adds the rebuilding step in create_pod_yaml_with_private_image() for `qemu-se`.

1. Use a container image that supports "ps --user 1000 -f".
2. Execute that command using:
sh -c "ps --user 1000 -f"
instead of passing additional arguments to sh:
sh -c ps --user 1000 -f

Keep track of individual exec args instead of joining them in the
policy text. Verifying each arg results in a more precise policy,
because some of the args might include space characters.
This improved validation applies to commands specified in K8s YAML
files using:
- livenessProbe
- readinessProbe
- startupProbe
- lifecycle.postStart
- lifecycle.preStop

The only kernel built for measured rootfs was the kernel-tdx-experimental,
so this test only ran in the qemu-tdx job runs the test.
In commit 6cbdba7 we switched all TEE configurations to use the same kernel-confidential,
so rootfs measured is disabled for qemu-tdx too now.
The VM still fails to boot (because of a different reason...) but the bug
in the assert_logs_contain, fixed in this PR was masking the checks on the logs.
We still have a few open issues related to measured rootfs and generating
the root hash, so let's skip this test that doesn't work until they are looked at
