Implement Rails scaffolding for Core Security & Compliance page

Why are we doing this work

This is the initial simplest first step to creating a static Security & Compliance page for core users - setting up the scaffolding for a new page.

Open questions

• How do we create a CE route that does not override the EE version of that same route?

Relevant links

• Design Issue
• Technical Discovery
• Equivalent MR for original EE version

Non-functional requirements

• [-] Documentation: TBD
• Feature flag: secure_security_and_compliance_configuration_page_on_ce
• Testing

Implementation plan

frontend

• Define CE configuration_controller.rb controller, mirroring EE version
• Guard controller behind core_security_compliance_page feature flag, disabled by default
• Define CE route for controller (be careful not to override EE route)
• Add HAML view entry point
