OCPNODE-4179: Migrating test case OCP-80983 from openshift-tests-private to origin

[Chandan9112]

Adds automated test case OCP-80983 migrated from openshift-tests-private. The test validates:

• All nodes are in Ready state
• Cgroup version is v2 (cgroup2fs) on worker nodes
• Kernel arguments include cgroupv2 parameters
• API server rejects setting cgroupMode to v1

Here is the test case link: Polarian-80983

It passed successfully while executing on a live OCP 4.21 cluster:
