894dcb7c1c app/vmselect/promql: improve further the accuracy of buckets_limit() function 
The accuracy is increased by mergin the smallest bucket with the smallest adjacent bucket.

215eba0b82 app/vminsert: flush bufs if needed after the current row is added 
Previously the data for the added row could be overwritten by the flush
before the row addition is complete.

edb1eca6f1 app/vmselect/promql: avoid dropping inf bucket in buckets_limit 
The `le="inf"` bucket must be preserved in order to maintain the maximum level of accuracy.

bb161497cf app/vmselect/promql: improve the accuracy of buckets_limit(k, buckets) function 
Now it properly merges the bucket with the previous bucket after deletion.

994fa2f3bf 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.

3e557c9861 app/vmselect/promql: add rate_over_sum(m[d]) function to MetricsQL, which returns rate over sum of m values over d duration 
Something like `sum_over_time(m[d]) / d`, but more accurate.

b1f6843bd0 app/vmselect/promql: allow setting [d] window smaller than the interval between raw points for avg_over_time 
This makes `avg_over_time` behavior consistent with `sum_over_time` and `count_over_time` behaviors.

039c9d2441 lib/storage: respect -search.maxQueryDuration when searching for time series in inverted index

e4303d3d21 lib/storage: prevent possible race condition when all the goroutines exit Storage.AddRows, before goroutines other goroutines are blocked on searchTSIDsCond inside Storage.searchTSIDs 
This condition may occur after the following sequence of events:

1) A goroutine enters the loop body when len(addRowsConcurrencyCh) == cap(addRowsConcurrencyCh) inside Storage.searchTSIDs.
2) All the goroutines return from Storage.AddRows.
3) The goroutine from step 1 blocks on searchTSIDsCond.Wait() inside the loop body.

The goroutine remains blocked until the next call to Storage.AddRows, which calls searchTSIDsCond.Signal().
This may take indefinite time.

e00cfc854d app/vmselect/promql: skip the first value in time series passed to increase() if it exceeds by more than 10x the delta between the next value and the first value 
This should prvent from inflated `increase()` results for time series that start from big initial values.
Such cases may occur when a label value changes in a metric without counter reset.
