[FLINK-4840] [metrics] Measure latency of record processing and expose it
as a metric
This PR introduce record processing time metric for measuring a task
running performance. The latency is processing time cost of all chained
operator for a task.
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
