[FLINK-4773] Intoduce OperatorIOMetricGroup
This PR introduces the OperatorIOMetricGroup, which encapsulates the
insantiation of numRecordsIn/Out counters. For clarity purposes the
IOMetricGroup class was renamed to TaskIOMetricGroup.
The underlying reasoning for this change is the reuse of specific operator
counters for the task (first operator numRecordsIn == task recordsIn). With
this class we can more easily do this within the metric system.
