> OpenTelemetry Java agent instrumentation

The dropwizard-metrics instrumentation for the dropwizard/codahale metrics library produces OpenTelemetry compliant versions of the metrics generated by the Dropwizard MetricRegistry.
The Dropwizard metrics API does not have a concept of metric labels/tags/attributes, thus the data produced by this integration might be of very low quality, depending on how the API is used in the instrumented application.
