> There are 2 cases where sources are considered idle and should emit an idle {{StreamStatus}}
downstream, taking Kafka consumer as example:
> - The source instance was not assigned any partitions
> - The source instance was assigned partitions, but they currently don't have any data.
> For the second case, we can only consider it idle after a timeout threshold. It would
be good to make this timeout user configurable besides a default value.
