    k8s-cni-cache-cleanup: use ActiveEnterTimestamp

    The script in k8s-cni-cache-cleanup is failing to run
    because 'WatchdogTimestamp' no longer exists.

    Instead we use another timestamp, namely ActiveEnterTimestamp.

    Test Plan:

    PASS: Lock and unlock the controller and verify that the cleanup
          works properly

    PASS: Launch pods using extra cni interfaces and make sure
          they work properly using specific test cases
