[jira] [Created] (KAFKA-10217) Move nodeLevelSensor and storeLevelSensor methods from StreamsMetricsImpl to StreamsMetrics

John Roesler created KAFKA-10217:
------------------------------------

             Summary: Move nodeLevelSensor and storeLevelSensor methods from StreamsMetricsImpl to StreamsMetrics
                 Key: KAFKA-10217
                 URL: https://issues.apache.org/jira/browse/KAFKA-10217
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: John Roesler


StreamsMetricsImpl contains several convenience methods for safely registering sensors at different levels of granularity. We added them as internal methods because we weren't sure of their stability and utility. Now, they've been in use for quite a while and seem to be stable.

We should move them up into the public API so that custom stores and processor implementations can also benefit from their safety.

Implementing this feature should also allow us to drop the adaptor function: `org.apache.kafka.streams.processor.internals.ProcessorContextUtils#getMetricsImpl`
