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).
