Introduces the Oracle CNE User Interface (UI).

The Oracle CNE UI provides a web-based interface to manage the maintenance and installation of Kubernetes cluster resources, and applications.

The UI runs in the Kubernetes cluster as a deployment named ui, running in the ocne-system namespace. A deployment named ocne-catalog also runs in the ocne-system namespace to serve the application catalog.

The UI is based on the open source Kubernetes UI Headlamp application. For more information on the Headlamp project, see the upstream Headlamp documentation.
