test(resource): add OpenShift cgroup v2 QoS test cases (#2359)

Add test coverage for Guaranteed and BestEffort QoS classes using cgroup v2
  systemd slice paths from OpenShift with CRI-O runtime:

  - Guaranteed QoS: kubepods-pod<uid>.slice (no QoS subdirectory)
  - BestEffort QoS: kubepods-besteffort.slice with CRI-O

  These test cases cover container detection patterns not previously tested
  for CRI-O in OpenShift environments.
