Describe the issue you're reporting

I think it makes sense to expose the otelcol_exporter_queue_batch_send_size metric when telemetry verbosity is set to detailed level, consistent with the existing otelcol_exporter_queue_batch_send_size_bytes metric.

The otelcol_exporter_queue_batch_send_size histogram metric generates bucket metrics (one per bucket boundary) which can result in high cardinality. When multiplied across multiple exporters in a collector deployment, this can significantly increase metric cardinality.

So I think it makes sense to change the verbosity level for the metrics. Since it is in Development, it guess it is ok.
