458d412bb6 app/vmselect/netstorage: adaptively adjust the maximum inmemory file size for storing temporary blocks
The maximum inmemory file size now depends on `-memory.allowedPercent`.
This should improve performance and reduce the number of filesystem calls
on machines with big amounts of RAM when performing heavy queries
over big number of samples and time series.

dcce92c63c app/vmselect/promql: add lifetime(q[d]) function, which returns the lifetime of q over d in seconds.
This function is useful for determining time series lifetime.
`d` must exceed the expected lifetime of the time series, otherwise
the function would return values close to `d`.

8c2158af24 all: use workingsetcache instead of fastcache
This should reduce the amount of RAM required for processing time series
with non-zero churn rate.

The previous cache behavior can be restored with `-cache.oldBehavior` command-line flag.

1d4ddadbb1 app/vmselect/promql: further increase the allowed jitter for scrape interval
Real-world production data shows higher jitter than 1/8 of scrape interval.
This may results in gaps on the graph. So increase the allowed jitter to 1/4
of scrape interval in order to reduce the probability of gaps on the graphs
over time series with high jitter for scrape_interval.

ade7bc30db app/vmselect/promql: tolerate higher jitter in scrape interval
