Add generic count down mechanism #3910

In our code we often need to wait for multiple events to happen up to a timeout (mainly in the node acknowledgement logic), and we then notify some listener. We usually do it using an AtomicInteger to count down and an AtomicBoolean to check whether the notification has already been sent.

It would be nice to have a single way to achieve this, having a class (e.g. CountDown) that exposes this behaviour, which can be thoroughly tested and used whenever we need to.
