+* Add OpenTelemetry Metrics API and Metrics SDK support. This is currently
+  experimental and may change. With this change, you may use the OpenTelemetry
+  Metrics API to create custom metrics and the APM agent will ship those
+  metrics to APM server. As well, you may use the OpenTelemetry Metrics SDK
+  and the APM agent will automatically add a MetricReader to ship metrics to
