55d728c849 lib/{decimal,encoding}: optimize float64<->decimal conversion for arrays with zeros or ones 
Time series with only zeros or ones frequently occur in monitoring, so it is worth optimizing their handling.

808fc0971f lib/{encoding,decimal}: add benchmarks for blocks containing zeros or ones 
Time series with such values are quite common in monitoring space,
so it would be great to have benchmarks for them.

c66a691593 app/vmselect/prometheus: add -search.maxLookback command-line flag for overriding dynamic calculations for max lookback interval 
This flag is similar to `-search.lookback-delta` if set. The max lookback interval is determined dynamically
from interval between datapoints for each input time series if the flag isn't set.

The interval can be overriden on per-query basis by passing `max_lookback=<duration>` query arg to `/api/v1/query` and `/api/v1/query_range`.

956fdd89d3 app/vmselect/promql: take into account the previous point when calculating max_over_time and min_over_time 
This lines up with `first_over_time` function used in `rollup_candlestick`, so `rollup=low` always returns
the minimum value.
