Change "Track *" to "Monitor" in our representation of CISA's tree

[ahouseholder]

Is your feature request related to a problem? Please describe.

CISA's adoption of SSVC resulted in their own customized outcome set that they use internally. However, some of the terminology used is highly idiosyncratic to their particular environment as a CSIRT with National Responsibility. In particular, terms like "Track *" have no significant meaning outside of their environment.

We include in our code and documentation examples derived from CISA's SSVC implementation. However, it's not necessary for us to retain their exact terminology if we can generalize concepts to be more applicable to other users of SSVC.

Describe the solution you'd like

The suggestion here is to replace "Track *" with something more generally understood, like "Monitor".

Additional context

This change would require us to modify at least:

• the json representation of the CISA model
• the CISA outcome group in the python code (which will flow down to the examples in https://certcc.github.io/SSVC/reference/code/outcomes/?h=cisa )

Note

Resolution of this issue is only intended to affect files associated with the https://github.com/CERTCC/SSVC repository.

Subsequent changes to CISA's SSVC information, the CISA SSVC Calculator etc., if any, will need to be coordinated through CISA staff.
