The ReportingPolicy enum is used in ScalarMetricOptions to conditionally export metrics, but ScalarMetricOptions::reportingPolicy is only checked before exporting metrics via OpenTelemetry right now. It is not checked before exporting serverStatus metrics in the OtelMetricsServerStatusAdapter. As a result, reporting of the same metric in serverStatus vs. OTel can be inconsistent.

Update the metrics API to conditionally export serverStatus metrics according to the provided ReportingPolicy.
