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

             Summary: Refactor MetricRegistry delimiter retrieval into separate interface
                 Key: FLINK-14351
                 URL: https://issues.apache.org/jira/browse/FLINK-14351
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Metrics
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
             Fix For: 1.10.0


The MetricRegistry offers a few methods for retrieving configured delimiters, which are used a fair bit during scope operations; however other methods aren't being used in these contexts.

Hence we could reduce access and simplify testing by introducing a dedicated interface for these methods that the registry extends.
