      - Adjust ETE runner for security tests

        This patch adds gathering data which cannot be easily obtained from
        within "robot" pod (without granting it access to "kubectl" tool and as
        a side effect - cluster modifications).

        It introduces dependency to python3 on operator's machine (to convert
        "kubectl" tool filtered output to JSON).
