feat(cve_to_elastic.py): add script that copies all CVE entries to elastic

* this script parses the cve-summary.json
* the json is modified and reformated
* the json objects a pushed to elastic

NOTE: There is a modification necessary on how the cve-summary is created.
I will try to get this upstream.
