Great idea.

> When reading from Kinesis streams, one of the most valuable metrics is
> "MillisBehindLatest" (see
> https://github.com/aws/aws-sdk-java/blob/25f0821f69bf94ec456f602f2b83ea2b0ca15643/aws-java-sdk-kinesis/src/main/java/com/amazonaws/services/kinesis/model/GetRecordsResult.java#L187-L201).
> Flink should use its metrics mechanism to report this value as a gauge,
> tagging it with the shard id.
