zenador	191bf9055b	Handle more arithmetic operators for native histograms (#12262 ) Handle more arithmetic operators and aggregators for native histograms This includes operators for multiplication (formerly known as scaling), division, and subtraction. Plus aggregations for average and the avg_over_time function. Stdvar and stddev will (for now) ignore histograms properly (rather than counting them but adding a 0 for them).

beorn7	cf698f71e5	Add an explanation for the quantile aggregation operator Sadly, just linking to the Histogram best practice document, as done for `histogram_quantile`, would be confusing here because the best practice document only deals with quantiles in the context of Histograms and Summaries, which is very different from the context of the `quantile` aggregator and `quantile_over_time` function, which is already a source of a lot of confusion. Thus, I think the least bad solution is to add a short explanation in this section directly. There isn't even a good resource on the internet we can link to. A lot of statisticians use φ-quantiles, but they don't have a generally accepted name for it. I have added the explanation after the other detailed explanations of `count_values`, `topk` and `bottomk`. I think that fits quite nicely into the flow.
