Fix deprecations around ListenableFuture (#3865)

Browse Source 
* Fix deprecations around ListenableFuture

SF has deprecated a `ListenableFuture` and API around it

* Migrate to `CompletableFuture` everywhere a `ListenableFuture` has been used
* Suppress a deprecation for `ListenableFuture` keeping the functionality until the next version
* Resolve deprecations nad removals from the latest Spring for Apache Kafka
* Fix documentation for the `ListenableFuture` in favor of `CompletableFuture`

NOTE: the AMQP module is left as is until `ListenableFuture` deprecation is resolved in Spring AMQP

* * Restore some `ListenableFuture` test for messaging gateway
