61e956e175 app/victoria-metrics: add a test for max_lookback=<duration> query arg

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`.

c1cf7d9f93 lib/storage: add tests for mergeTagToMetricIDsRows and return the original items if the function breaks items` ordering. 
This should save from data corruption issues revealed in the previous releases up to v1.28.0-beta5.

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.

`decreases_over_time(q[d])` returns the number of `q` decreases during the given duration `d`.

b986516fbe lib/storage: create and use lib/uint64set instead of map[uint64]struct{} 
This should improve inverted index search performance for filters matching big number of time series,
since `lib/uint64set.Set` is faster than `map[uint64]struct{}` for both `Add` and `Has` calls.
See the corresponding benchmarks in `lib/uint64set`.

0686ac52c3 lib/{storage,mergeset}: merge tag->metricID rows into tag->metricIDs rows for common tag values 
This should improve lookup performance if the same `label=value` pair exists
in big number of time series.
This should also reduce memory usage for mergeset data cache, since `tag->metricIDs` rows
occupy less space than the original `tag->metricID` rows.

a544f49c2b lib/storage: optimize selecting all the metricIDs by scanning MetricID->TSID entries instead of tag->MetricID entries 
The number of MetricID->TSID entries is smaller than the number of tag->MetricID entries
and MetricID->TSID entries are usually shorter than tag->MetricID entries.
This should improve performance when selecting all the metricIDs.
