GH-256: Mark RetryConfiguration as infrastructure bean

Fixes: https://github.com/spring-projects/spring-retry/issues/256

This suppresses the info message "Bean 'org.springframework.retry.annotation.RetryConfiguration' of type [org.springframework.retry.annotation.RetryConfiguration] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)" during the Spring context start.
