Transition dependencies from cve.mitre.org to cve.org

Starting in September 2021 cve.mitre.org will be faded out for a new cve.org including new services on how to get and submit CVEs.

Announce; https://cve.mitre.org/news/archives/2021/news.html#September022021_CVE_Website_Transitioning_to_New_Web_Address_-_CVE.ORG

We heavily depend on data from MITRE and need to prepare tracker and tooling to cope with the new services on cve.org
