> For some split assignment strategy, the enumerator/assigner needs to track the completed splits to advance watermark for event time alignment or rough ordering. Right now, `RequestSplitEvent` for FLIP-27 source doesn't support pass-along of the `finishedSplitIds` info and hence we have to create our own custom source event type for Iceberg source. 
> Here is the proposal of add such optional info to `RequestSplitEvent`.
> {code}
> public RequestSplitEvent(
>     @Nullable String hostName, 
>     @Nullable Collection<String> finishedSplitIds)
> {code}
