[FLINK-4514][kinesis-connector] Handle unexpected ExpiredIteratorExceptions Handle any unexpected {{ExpiredIteratorException}}s on {{getRecords()}} calls be refreshing the failing shard iterator with a new one. A user reported this issue when replaying Kinesis data over a wide time span, but then the consumer was back to normal after the consumer caught up with the latest data. I tried to reproduce the exception, but have come short to be able to reproduce. The behaviour seems to be inconsistent. Therefore, this change treats the exception as "unexpected" by simply catching the exception and refreshing the iterator. There's actually no guarantee of how much time had passed between each getRecords() request anyways, so this is a simple way to handle this.
