`allow_interactive_exec` requires a sandbox-name annotation, however
this is only added for pods by genpolicy. Other pod-generating resources
have unpredictable sandbox names.
This patch instead uses a regex for the sandbox name in genpolicy, based
on the specified metadata and following Kubernetes' naming logic. The
generated regex is then used in the policy to correctly match the
sandbox name.

Exclude 'cgroup' namespace from namespace checks during `allow_linux`
validation. This complements the existing exclusion of the 'network'
namespace.
As runtime-rs has specific cgroup namespace configurations, and excluding it from
policy validation ensures parity between runtime-rs and runtime-go implementations.
This allows focusing validation on critical namespaces like PID, IPC, and MNT, while
avoiding potential policy mismatches due to another cgroup namespace management by
the runtime-rs.

Add `normalize_namespace_type()` function to map "mount"
(case-insensitive) to "mnt" while keeping other values unchanged.
This ensures namespace comparisons treat "mount" and "mnt" as
equivalent.

- Use set comparison to ignore ordering differences when matching
capabilities.
- Add normalization to strip "CAP_" prefix to support both CAP_XXX and
XXX formats.
This makes capability matching more robust against different ordering

This change introduces a new command line option `--vm`
to boot up a pod VM for testing. The tool connects with
kata agent running inside the VM to send the test commands.
The tool uses `hypervisor` crates from runtime-rs for VM
lifecycle management. Current implementation supports
Qemu & Cloud Hypervisor as VMMs.
In summary:
- tool parses the VMM specific runtime-rs kata config file in
/opt/kata/share/defaults/kata-containers/runtime-rs/*
- prepares and starts a VM using runtime-rs::hypervisor vm APIs
- retrieves agent's server address to setup connection
- tests the requested commands & shutdown the VM

When the network interface provisioned by the CNI has static ARP table entries,
the runtime calls AddARPNeighbor to propagate these to the agent. As of today,
these calls are simply rejected.
In order to allow the calls, we do some sanity checks on the arguments:
We must ensure that we don't unexpectedly route traffic to the host that was
not intended to leave the VM. In a first approximation, this applies to
loopback IPs and devices. However, there may be other sensitive ranges (for
example, VPNs between VMs), so there should be some flexibility for users to
restrict this further. This is why we introduce a setting, similar to
UpdateRoutes, that allows restricting the neighbor IPs further.
The only valid state of an ARP neighbor entry is NUD_PERMANENT, which has a
value of 128 [1]. This is already enforced by the runtime.
According to rtnetlink(7), valid flag values are 8 and 128, respectively [2],
thus we allow any combination of these.

- "confidential_emptyDir" becomes "emptyDir" in the settings file.
- "confidential_configMap" becomes "configMap" in settings.
- "mount_source_cpath" becomes "cpath".
- The new "root_path" gets used instead of the old "cpath" to point to
the container root path..
- "confidential_guest" is no longer used. By default it gets replaced
by "enable_configmap_secret_storages"=false, because CoCo is using
CopyFileRequest instead of the Storage data structures for ConfigMap
and/or Secret volume mounts during CreateContainerRequest.
- The value of "guest_pull" becomes true by default.
- "image_layer_verification" is no longer used - just CoCo's guest pull
is supported.
- The Request input files from unit tests are changing to reflect the
new default settings values described above.
- tests/integration/kubernetes/tests_common.sh adjusts the settings for
platforms that are not set-up for CoCo during CI (i.e., platforms
other than SNP, TDX, and CoCo Dev).
