fedcode-next: Create curation queue for VulnerableCode data enrichment

[pombredanne]

A curation queue for data enrichment should ensure we curate key vulnerability attributes such as PURL, VERS, severity, weaknesses, scoring, remediation or mitigation. Eventually the queue should be sorted such that we can focus on the more important issues first, either because a vulnerability may be more important, or because we are missing critical data points:

• fedcode-next: Core UI and models to expose a sorted vulnerabilities curation queue #1716
• fedcode-next: Code, UI and models to curate PURL and VERS package version range for packages affected and fixing a vulnerability #1717
• fedcode-next: Code, UI and models to assign and qualify the weakness exposed by a CVE (or CWE) #1718
• fedcode-next: Code, UI and models to curate severity scoring #1719
• fedcode-next: Code, UI and models to expose and curate extra mitigation possibilities #1720
