Tested: manually

A local OTC w/ debug exporter shows metrics from the examples/metrics demo like:

Descriptor:
     -> Name: otelsdk_exporter_sent_wire
     -> Description: Number of bytes sent on the wire by the component.
     -> Unit: bytes
     -> DataType: Sum
     -> IsMonotonic: true
     -> AggregationTemporality: Delta
NumberDataPoints #0
Data point attributes:
     -> exporter: Str(otel_sdk_metric_otlp)
     -> method: Str(/opentelemetry.proto.collector.metrics.v1.MetricsService/Export)
