Consider adding tracker data types for CVE maintenance

[Chris-Turner-NIST]

User Story:

Throughout the Vulnerability life cycle there are a series of events that would be valuable to track for historical, maintenance and academic purposes. Should we consider adding these types of information?

Ex:
ID Date
Public Disclosure Date
Patched Date
etc.

Many examples of this can be found within the CVRF documentation

Goals:

Review important data types that are useful for historical, academic and program maintenance. Provide either a new object and properties or series of properties that should be associated to an existing object.
Update all documentation to reflect the additional data types.

Dependencies:

N/A
