1c69f4eadc app/vmselect/promql: tune automatic window adjustement 
Increase the windows adjustement for small scrape intervals,
since they usually have higher jitter.

8d93b15b86 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.

f090b2e917 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`.

4aaa5c2efc app/vmselect/promql: allow adjusting window for default rollup function
