2ac5f00d98 app/vmselect: propagate errors from vmstorage to response to the client if -search.denyPartialResponse command-line flag is set 
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/891

is based on a partial data because some of vmstorage nodes weren't available during query processing.

99786c2864 app/vmselect/prometheus: add -search.maxLookback command-line flag for overriding dynamic calculations for max lookback interval

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`.
