06 - Create domains, projects, users and roles in OpenStack

Identity (Keystone) is OpenStack’s authentication and authorization service. In this step I prepare the minimal Identity configuration we need to continue the installation and to test OpenStack. Although the default domain already exists after keystone-manage bootstrap, I explicitly create the projects and users we use in the guides: service (for service users) and demo (for non‑admin user tests). I also create an example role and assign it to the demo user.
