Java 8 CompletableFuture, Stream API return types for spring-data repositories

A VFuture is a handle to the result of an asynchronous computation. It captures the effects of latency and failure: it is completed once the computation finishes (either successfully or with a failure). The implementation uses virtual threads for producing the future's result.
