> Currently it is required to store the key of a keyBy() in the processElement 
> method to have access to it in the OnTimerContext.
> This is not so good as you have to check in the processElement method for 
> every element if the key is already stored and set it if it's not already set.
> A possible solution would adding OnTimerContext#getCurrentKey() or a similar 
> method. Maybe having it in the open() method could maybe work as well.
