> 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.
