#19440 replace Scala Future usage with CompletionStage in javadsl

Browse source 
This entails:

  * adding akka.pattern.PatternCS.* to enable ask etc. with
    CompletionStage
  * changing RequestContext to offer an ExecutionContextExecutor for the
    CompletionStage.*Async combinators
  * splitting up akka.stream.Queue for JavaDSL consistency
