Structured concurrency on top of plain Scala Future-s

Here is a blog post with a sketch API description.

## Structured concurrenty with Scala Future
  
### FutureScope

I sketched a [small API](https://github.com/rssh/dotty-cps-async/tree/master/jvm/src/test/scala/futureScope), how structured on top of plain Scala Futures can look.
The idea is to have a scope context, which can be injected into an async block, and a set of structured operations defined for scope, automatically canceled when the main execution flow is terminated.

```Scala
def  doSomething = async[Future].in(Scope){

    val firstWin = Promise[String]()
    firstWin completeWith FutureScope.spawn{
           firstActivity()
    }
    firstWin completeWith FutureScope.spawn{
          secondActivity()
    } 

    await(firstWin.future)
      //  unfinished activity will be canceled here.
