app/vmselect/promql: add buckets_limit(k, buckets)
function, which limits the number of buckets per time series to k
...
This function works with both Prometheus-style and VictoriaMetrics-style buckets.
The function removes buckets with the lowest values in order to reserve the highest precision.
The function is useful for building heatmaps in Grafana from too big number of buckets.

values over d
