DL-124: Use Java8 Future rather than twitter Future

Switch to use Java8 CompletableFuture, to reduce dependencies introduced by twitter future and make it more friendly to users (users don't think of using which version of scala).

This change is based on #132 . Gitsha ce0686e is the change to review.

The changes:

- Change Future to CompletableFuture
- Map to thenApply
- flatMap to thenCompose
- Added a FutureEventListener, and switch addEvenListener to whenComplete (or whenCompleteAsync)
- setValue to complete
- setException to completeExceptionally
- add rescue, ignore, ensure to FutureUtils as util functions.
