Multi Repository configuration

Multiple repository factories try to register all repository interfaces with them - which doesn't work very well. Especially because spring-boot does a lot of auto-magic behind the curtain via the implicit existing @EnableJpaRepositories.

The solution is to tell JPA and DynamoDB which repositories they are responsibility for (which then also drives which entities are registered):

For Spring-Boot:

@SpringBootApplication
@EnableJpaRepositories(includeFilters = {
	@ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = {CustomerRepository.class})
})
@EnableDynamoDBRepositories(includeFilters = {
	@ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = {DeviceValueRepository.class})
})
public class Application {

Same for a configuration class:

@Configuration
@EnableJpaRepositories(includeFilters = {
//or use basePackages or excludeFilters
	@ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = {CustomerRepository.class})
})
@EnableDynamoDBRepositories(includeFilters = {
//or use basePackages or excludeFilters
	@ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = {DeviceValueRepository.class})
})
public class AppConfig {
