zhuhaifeng updated FLINK-4840:
------------------------------
Description:
We should expose the following Metrics on the TaskIOMetricGroup:
1. recordProcessLatency(ms): Histogram measuring the processing time per record
of a task. It is the processing time of chain if a chained task.
2. recordProcTimeProportion(ms): Meter measuring the proportion of record
processing time for infor whether the main cost

We should expose the following Metrics on the OperatorIOMetricGroup:
1. latency(ms): record processing time as a histogram metric.
2. procTimeCostPerSecond(ms): record processing time accumulated per second,
it measure record processing percentage to check if it's a main time costing
3. delay(ms): the time between upstream emit record and downstream start
record processing
> Measure latency of record processing and expose it as a metric
