Sample with Spring Cloud Config Client + Server

[rwinch]

We should demonstrate testjars working with Spring Cloud Config Client + Server

Spring Framework

• DynamicPropertyRegistrar should work outside of the scope of tests since Spring Cloud needs to dynamically register properties outside of test
• We need to be able to order the invocation of DynamicPropertyRegistrar.accept(DynamicPropertyRegistry). Perhaps this can be done by getting all instances and then sorting by ordered in DynamicPropertyRegistrarBeanInitializer

Spring Boot Testjars

• Support Registering Additional Classes with the ApplicationContext #71
• Add @ConfigServerUri #74

Spring Cloud

• Spring Cloud needs to add ConfigServerDynamicPropertyRegistrarImportBeanDefinitionRegistrar
• Spring Cloud Config Needs to allow disabling ConfigServerConfigDataLoader in favor of ConfigServerDynamicPropertyRegistrarImportBeanDefinitionRegistrar
• Consider applying @EnableConfigServer automatically to eliminate the need for adding additionalBeanClassNames
