----------------------------------------

             Summary: Add default implementations for all MetricGroup methods accepting ints
                 Key: FLINK-21758
                 URL: https://issues.apache.org/jira/browse/FLINK-21758
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Metrics
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
             Fix For: 1.13.0


The MetricGroup interface contains variations of methods that accept either a string or int as the group/metric names.

In practice all implementations just convert the int to a string anyway, which we could also setup as the default implementation.
