Revise usage of @EnableConfigurationProperties

1. use `@EnableConfigurationProperties` to register configuration properties beans if the bean name is not relevant.
2. remove `@EnableConfigurationProperties` without specified value if the `@Configuration` class doesn't contain any `@ConfigurationProperties` bean.
