ec9bf39b5b 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.

d0d258b314 app/vmselect: limit the default value for -search.maxConcurrentRequests, so it plays well on systems with more than 16 vCPUs

This will give more chances for executing insert path.
