JIRA: https://jira.spring.io/browse/INT-2549
* Add `expectReply` property into the `OperationInvokingMessageHandler`
to align the one-way and request-reply behavior with all other similar
components in Spring Integration
* Ignore an operation invocation result in case of `expectReply == false`
and log warning
* Provide some refactoring into the `OperationInvokingMessageHandler`
to fix Sonar complains about complexity
**Cherry-pick to 5.0.x, 4.3.x**
