Auto-generate the policy and then simulate attacks from the K8s
control plane by modifying the test yaml files. The policy then
detects and blocks those changes.
These test cases are using K8s Jobs. Additional policy failures
will be injected using other types of K8s resources - e.g., using
Pods and/or Replication Controllers - in future PRs.

Check from:
- k8s-exec-rejected.bats
- k8s-policy-set-keys.bats
if policy testing is enabled or not, to reduce the complexity of
run_kubernetes_tests.sh. After these changes, there are no policy
specific commands left in run_kubernetes_tests.sh.
add_allow_all_policy_to_yaml() is moving out of run_kubernetes_tests.sh
too, but it not used yet. It will be used in future commits.

Delete the debugger pod created during the test, rather than already
existing debugger pods.
Also, send the output of "kubectl delete" to stderr, just in case it's
useful for debugging.

1. add_requests_to_policy_settings allows one or more ttrpc requests
from the Host to the Guest. Example:
add_requests_to_policy_settings "${policy_settings_dir}" \
"ReadStreamRequest" "WriteStreamRequest"
2. add_copy_from_host_to_policy_settings allows executing on the Guest
the commands initiated behind the scenes by "kubectl cp" from the
Host to the Guest. Example:
add_copy_from_host_to_policy_settings "${policy_settings_dir}"
3. add_copy_from_guest_to_policy_settings allows executing on the Guest
the commands initiated behind the scenes by "kubectl cp" from the
Guest to the Host. Example:
add_copy_from_guest_to_policy_settings "${policy_settings_dir}" \
"/tmp/file.txt"

Enable AUTO_GENERATE_POLICY for one of the Kata CI K8s test platforms.
Additional platforms will be enabled after testing them.
When AUTO_GENERATE_POLICY is enabled, create genpolicy settings that
are common for all tests. Some of the tests will make temporary copies
of these common settings and customize them as needed.

Bring the setup_common() from CCv0 branch test's
integration/kubernetes/confidential/tests_common.sh. It should be used
to reduce boilerplates on the setup() of the tests.
Unlike the original code, this won't export the `test_start_time` variable
as it wouldn't be accurate to grab logs from the worker nodes due
date/time mismatch between the running tests machine and the worker
node. The function export the `node` variable which holds the name of
a random node which has kata installed. Apart from that, it exports the
`node_start_time` which capture the date/time when the test started,
relative to the `node`.
Tests that should inspect the logs can schedule pods/resources to the `node`
and use `node_start_time` as the value reference to grep the logs.

The exec_host() simply fails on cluster with multi-nodes because
`kubectl get node -o name" will return a list o names. Moreover, it will
return control nodes names which usually don't have kata installed.

The introduced get_one_kata_node() returns the first node that
has the kata-runtime=true label, i.e., supposedly a node with
kata installed.
This is useful for tests that should run on a determined worker
node on a multi-nodes cluster.

The k8s.gcr.io is deprecated for a while now and has been redirected to
registry.k8s.io. However on some bare-metal machines in our testing
pools that redirection is not working, so let's just replace the
registries.

(cherry picked from commit b2c3bca558c38deff2117d5909d9071c23c05590)
We've faced this as part of the CI, only happening with the CRI-O tests:
```
not ok 1 Test readonly volume for pods
# (from function `exec_host' in file tests_common.sh, line 51,
# in test file k8s-file-volume.bats, line 25)
# `exec_host "echo "$file_body" > $tmp_file"' failed with status 127
# [bats-exec-test:38] INFO: k8s configured to use runtimeclass
# bash: line 1: $'\r': command not found
#
# Error from server (NotFound): pods "test-file-volume" not found
```
I must say I didn't dig into figuring out why this is happening, but we
may be safe enough to just trail the '\r', as long as all the tests keep
passing on containerd.

Makes it so that `setup.sh` doesn't make changes in
`runtimeclass_workloads/` directly. Instead we treat that as a template
directory and we use the new directory `runtimeclass_workloads_work/` as
a work dir.
This has two advantages:
* Allows rerunning tests without the assumption that `setup.sh` must be
idempotent. E.g. the `set_runtime_class()` step would break.
* Doesn't pollute your git environment with a bunch of changes when
developing.

Now that the infra for running dragonball tests has been enabled, let's
actually make sure to have them running on each PR.
The tests skipped are:
* `k8s-cpu-ns.bats`, as CPU resize doesn't seem to be yet properly
supported on runtime-rs

The first part of simplifying things to have all our tests using GitHub
actions is moving the k8s tests to this repo, as those will be the first
vict^W targets to be migrated to GitHub actions.
Those tests have been slightly adapted, mainly related to what they load
/ import, so they are more self-contained and do not require us bringing
a lot of scripts from the tests repo here.
A few scripts were also dropped along the way, as we no longer plan to
deploy kubernetes as part of every single run, but rather assume there
will always be k8s running whenever we land to run those tests.
It's important to mention that a few tests were not added here:
* k8s-block-volume:
* k8s-file-volume:
* k8s-volume:
* k8s-ro-volume:
These tests depend on some sort of volume being created on the
kubernetes node where the test will run, and this won't fly as the
tests will run from a GitHub runner, targetting a different machine
where kubernetes will be running.
* https://github.com/kata-containers/kata-containers/issues/6566
* k8s-hugepages: This test depends a whole lot on the host where it
lands and right now we cannot assume anything about that anymore, as
the tests will run from a GitHub runner, targetting a different
machine where kubernetes will be running.
* https://github.com/kata-containers/kata-containers/issues/6567
* k8s-expose-ip: This is simply hanging when running on AKS and has to
be debugged in order to figure out the root cause of that, and then
adapted to also work on AKS.
* https://github.com/kata-containers/kata-containers/issues/6578
Till those issues are solved, we'll keep running a jenkins job with
hose tests to avoid any possible regression.
Last but not least, I've decided to **not** keep the history when
bringing those tests here, otherwise we'd end up polluting a lot the
history of this repo, without any clear benefit on doing so.
