  - k8s: Validate API server excluded admission plugins

    This patch verifies if CIS Kubernetes Benchmark v1.3.0 section
    regarding master node configuration is satisfied (1.1.10).

    However, CIS Kubernetes Benchmark v1.3.0 mismatches official
    documentation: Kubernetes 1.10+ already provides safe defaults from
    security standpoint [1] (ONAP Casablanca uses 1.11).

    Deprecated admission control plugin flag has also been validated since
    it was still available in Kubernetes provided by Rancher [2].
