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`.

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.
