Bug report: Missing optional configuration parameter in event sources for Lambda

DestinationConfig is a configuration object that specifies the destination of an event (Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Kafka only) after Lambda processes it.

AWS Lambda now supports failed-event destinations for Kafka event source mappings. But the Lambda developer guide doesn't reflect this configuration parameter for MSK, self managed Apache Kafka, Kinesis or even DynamoDB streams. It can be added.
