Use @Configuration(proxyBeanMethods=false) (#1174)

* Use `@Configuration(proxyBeanMethods=false)`

Related to spring-projects/spring-integration#2988

For faster startup (and possibility to compile to native code with GraalVM)
use a `proxyBeanMethods = false` on all the `@configuration` classes
in the Framework
* Provide some other code style polishing

* * Upgrade dependencies, including Gradle
* More `exclude group: 'org.springframework'`
