GH-9617: @SuppressWarnings("removal") for ListenableFuture

Browse Source 
Fixes: #9617
Issue link: https://github.com/spring-projects/spring-integration/issues/9617

The `ListenableFuture` is marked `forRemoval` in Spring Framework.
So, fix the code base to use `@SuppressWarnings("removal")`.
Also, add a warning into logs that `ListenableFuture` support will be removed in `7.0`.

* Fix JavaDocs where `ListenableFuture` is mentioned in favor of `CompletableFuture`

@@ -618,9 +618,6 @@ There are two modes of operation when returning this type:
* When the async executor is explicitly set to `null` and the return type is `CompletableFuture` or the return type is a subclass of `CompletableFuture`, the flow is invoked on the caller's thread.
In this scenario, the downstream flow is expected to return a `CompletableFuture` of the appropriate type.
NOTE: The `org.springframework.util.concurrent.ListenableFuture` has been deprecated starting with Spring Framework `6.0`.
It is recommended now to migrate to the `CompletableFuture` which provides similar processing functionality.
