Feature: Remove deprecated generation profiles

[ewilkins-csi]

Description

During the release of 1.11, we marked several Fermenter profiles for deletion in 1.12. We should delete these profiles now, and all of the associated support that will no longer be necessary. See PR #575

DOD

Acceptance criteria required to realize the requested feature

• All profiles with the message "will be REMOVED in 1.12" are removed from profiles.json
• All targets which are no longer used after the profile deletion are removed from targets.json
• All template files which are no longer used after target deletion are removed
• TBD: What about baseline artifacts that are no longer ref'ed? (e.g. Data Access chart, Vault image)

Test Strategy/Script

How will this feature be verified?

References/Additional Context

We should update the generator_usage_generator.py script to help identify unused targets/templates.
