Request: Ability to add (private) user comments, sticky note, reminder text to a CVE

[MalfuncEddie]

Is your feature request related to a problem?
Feature:

It would be nice if a user could add some limited commentary to a cve. The easiest would be that the comment is private only to the user. Maybe it could be expanded in the future that the comment is visible to a group of users.

Use case:

1. Receive notification of a CVE
2. I analyze it and come to the conclusion that it is not present in the environment.
3. <insert a "rough weekend">
4. CVE gets updated
5. I analyze it and come to the conclusion that it is not present in the environment but forgot I already did this.

With the ability to a (private) comment to the cve:

1. Receive notification of a CVE:
2. I analyze it and come to the conclusion that it is not present in the environment.
3. Set a note "not present in my environment"
4. CVE gets updated
5. See I have a comment

Current "work around" (not invented by me) is a shared excel file where you enter the cve number and comment column.

Do you have a solution in mind, or a suggestion to improve OpenCVE?

I think (with my limited Django knowledge) that when you add a class CveComment(BaseModel): to
https://github.com/opencve/opencve/blob/dev/ncrocfer/v2/web/users/models.py

It should work on the backend part.
When V2 is released I will try to modify it and see how far I can get.
