Display CVSS vectors and allow their search

[TG1999]

We currently do not display CVSS vectors in the vulnerability details view and do not allow the the capability to search by a CVSS vector

I think using this may be a good start

>>> from cvss import CVSS3
>>> v = CVSS3("CVSS:3.0/AV:L/UI:N/AC:L/PR:H/C:N/I:L/A:H/S:C/E:U/RL:W/RC:X")
>>> v.as_json()
