> Timer state should now become part of the keyed state backend snapshot, i.e., 
> stored inside the managed keyed state. This means that we have to connect our 
> preparation for asynchronous checkpoints with the backend, so that the timers 
> are written as part of the state for each key-group. This means that we will 
> also free up the raw keyed state an might expose it to user functions in the 
> future.
