service: create CRUD with cerebrum error handling, no relation to organization

Motivation: The API should provide a functionality to create and modify a service.

Modifications: Extend the service model. Create enum for lifecycle status and authentication. Add the controller class and the repository interface. Use the cerebrum error handling for the service.

Result: Now it's possible to create, read (single or multiple (+PagingAndSorting)), update and delete Services via REST API calls.
