XPACK/Secure Elasticsearch Communications Support

[bionicspy]

There is no default support for secure elasticsearch parameters communications such as XPACK protected cluster. (suspect others like SHIELD and SearchGaurd protected clusters will have similar requirements)

(Verified workaround on Elasticsearch 5.6.3 with XPACK enabled)
Suggest adding additional (or potentially optional) dependency (pip install certifi) and add line
import certifi
to import section of import_testssl.sh_csv_to_ES.py

Note: When using non-public CA for elasticsearch cluster, you must also append CA (and Intermediate, if required) to certifi cacert.pem chain.
cat root-ca.pem >> /usr/lib/python3.4/site-packages/certifi/cacert.pem
cat intermediate-ca.pem >> /usr/lib/python3.4/site-packages/certifi/cacert.pem
(Tested Python 3.4 on CentOS 7.4)

Enables (XPACK enabled cluster with encrypted communications and authentication)
