FY22-Q2 Secure:Static Analysis KR - Establish Maintainers in Static Analysis projects
### Problem to solve
As a member of gitlab-org/gitlab~10690740, I want to know who to interact with to ship code and have more confidence in the types of scrutiny each change has received.
### Proposal
- [ ] [Formalize a maintainer program for Secure analyzers](https://gitlab.com/gitlab-org/secure/general/-/issues/52).
### Further details
This work builds on the groundwork laid in https://gitlab.com/gitlab-org/gitlab/-/issues/300358.
- [x] The proposal for adding a [Maintainers program in Static Analysis](https://gitlab.com/gitlab-com/www-gitlab-com/-/merge_requests/81120) needs to be finalized. It's out to the team for commentary and contribution.
- [x] Maintainers need to be encouraged to self-nominate for the trainee process.
- [ ] Trainee maintainers need to be worked through the process and converted into Maintainers for each project owned by Static Analysis.
- [x] Add `CODEOWNERS` files to projects-in-product which are owned by ~"group::static analysis"
#### Updated roles and permissions
- [x] Static Analysis Backend Engineers removed as direct members of https://gitlab.com/gitlab-org/security-products.
- [x] https://gitlab.com/gitlab-org/secure/static-analysis-be added as a group to be `Maintainers` for:
- [x] https://gitlab.com/gitlab-org/security-products/post-analyzers
- [x] https://gitlab.com/gitlab-org/security-products/security-report-schemas
- [x] https://gitlab.com/gitlab-org/security-products/ci-templates
- [x] https://gitlab.com/gitlab-org/security-products/danger-bot
- [x] https://gitlab.com/gitlab-org/security-products/security-product-templates
- [x] https://gitlab.com/gitlab-org/security-products/release
- [x] https://gitlab.com/gitlab-org/security-products/tests
- [x] https://gitlab.com/gitlab-org/security-products/dependencies
- [x] https://gitlab.com/gitlab-org/security-products/demos
- [x] SAST and Secret Detection analyzers in https://gitlab.com/gitlab-org/security-products/analyzers updates so `Developer+Maintainer` may merge into protected branches.
- [x] Trainee Maintainers (as indicated by related issues) added to `CODEOWNERS` files for the projects they indicated.
- [x] Verify SAST and Secret Detection projects in https://gitlab.com/gitlab-org/security-products/analyzers are set up to require CODEOWNERS approval prior to merge.
- [x] Update week 2 onboarding template so Static Analysis new starters aren't made `Developers` in https://gitlab.com/gitlab-org/security-products.
