Interface operation feature enhancements

1. API restructuring to enhance model and provide more capabilities.
2. Allowed multiple interface creation under same resource/service
3. Enhanced validations to align with updated model
4. API restructuring to align UI model with Tosca model
5. Enhanced Junit and code coverage.
