Refactored Layers Architecture To Be A Spring Boot Application. Issue #2450

[JabezBrew]

1. Rebuilt the entire module to become a spring boot app .
2. Changed the xml-based configuration to annotation-based. As such the applicationContext.xml file is no more and with the autoconfiguration that comes with the annotation-based config, an application context is created and beans are automatically created by spring boot to be injected where needed.
3. Used Spring's constructor injection to pass around needed objects.
4. Implemented deleteAll() methods for the CakeBakingServiceImpl to be used during testing. The deleteAll() methods, which are called before each tests using the @BeforeEach lifecycle annotation, was a way to adjust the tests in light of the singleton dependency injection of the CakeBakingServiceImpl bean
5. Implemented a CommandLineRunner to run the spring boot app when app starts. That's where initializeData() and cakeView.render() methods are called
6. And others.

@iluwatar sonarcloud's test coverage is a little bit too much. The tests in place should suffice
