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.

all: use workingsetcache instead of fastcache

This should reduce the amount of RAM required for processing time series
with non-zero churn rate.
