Downsample index API

Aggregates a time series (TSDS) index and stores pre-computed statistical summaries (min, max, sum, value_count and avg) for each metric field grouped by a configured time interval. For example, a TSDS index that contains metrics sampled every 10 seconds can be downsampled to an hourly index. All documents within an hour interval are summarized and stored as a single document in the downsample index.
