Issue XD-3517: Document direct binding 
As an s-c-d user, I'd like to refer to documentation on "direct binding", so I can use it as a reference to deploy a stream that includes directly bound modules. Example: {code} java -jar spring-cloud-stream-module-launcher/target/spring-cloud-stream-module-launcher-1.0.0.BUILD-SNAPSHOT.jar --modules=org.springframework.cloud.stream.module:time-source:1.0.0.BUILD-SNAPSHOT,org.springframework.cloud.stream.module:filter-processor:1.0.0.BUILD-SNAPSHOT,org.springframework.cloud.stream.module:filter-processor:1.0.0.BUILD-SNAPSHOT --args.0.fixedDelay=7 --args.1.expression='payload.contains("6")' --aggregate=true --spring.cloud.stream.bindings.output=filtered {code}
