Implementation

backend 3️⃣ - we'll have to add a lot of violation types

1. Add violation types to http://gitlab.com/gitlab-org/gitlab/blob/master/ee/lib/gitlab/compliance_management/violations
2. Make sure the GraphQL endpoint can pass the new types and any additional info needed for these types
3. Add new specs

   1. Protected branch: Link to branch (GlLink)
   2. CI status: Render ci status (reuse GitLab component)
   3. Code coverage report: Render report (reuse MR widget component)
   4. Security report: Render report (reuse MR widget component)
   5. Performance report: Render report (reuse MR widget component)
   6. Missing linked issue: Text body
