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.

4fb635b0c9 lib/storage: do not change timestamps to constant rate if values are constant or have constant delta 
This breaks the original timestamps, which results in issues like
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/120 and
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/141 .

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 
Allow jitter for up to 1/8 instead of 1/16 for the scrape interval.
This should imrpove graphs when `step` is smaller than the `scrape_interval`.
