- Add `/ee/spec/javascripts` for frontend maintainers.

- Add `/ee/lib/ee/gitlab/background_migration/` for DB maintainers.
- Add `/ee/lib/gitlab/database/` for DB maintainers.
- Add `/.gitlab/ci/docs.gitlab-ci.yml` for TW and EPE teams.
- Add EPE to `/.gitlab/ci/releases.gitlab-ci.yml` and
  `/scripts/frontend/`.
