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.
Fixes: #9395
