I am instrumenting our apps via OpenTelemetry SDK and write the metrics into Elastic via OpenTelemetry Protocol described in here: [OpenTelemetry native support | Elastic Observability [8.14] | Elastic](https://www.elastic.co/guide/en/observability/current/apm-open-telemetry-direct.html).

Is there any way to make the data stream/backing index for the metrics work as TSDS (Time series data stream described in [Time series data stream (TSDS) | Elasticsearch Guide [8.14] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/tsds.html))? I want to enable rollup/downsampling for our metrics data. Our server can't keep up with the resolution of the metrics and taking ages to query when the timespan is large.
