DATAREST-1543 - Deprecate RepositoryRestConfiguration.getCorsRegistry().

Browse Source 
Slightly tweaked the configuration model to rather handle the CorsRegistry via RepositoryRestConfigurer.configureRepositoryRestConfiguration(…) rather than RepositoryRestConfiguration itself. That allows moving of Spring WebMVC as a dependency in the core module.

The original methods exposing access to the CorsRegistry are now still available in deprecated form to not break existing clients.

Follow-up ticket: DATAREST-1542.
