app/vmselect/promql: allow to use 2x more memory for query processing in cluster mode compared to single-node mode
...
`vmselect` has no `vmstorage`-related caches. So it can use more memory for query processing compared to single-node VictoriaMetrics.

app/vmselect: add -search.cacheTimestampOffset command-line flag
...
This flag can be used for removing gaps on graphs if the difference between the current time
and the timestamps from the ingested data exceeds 5 minutes.
This is the case when the time between data sources and VictoriaMetrics is improperly synchronized.
