8f4790625d app/vmselect/promql: return the correct time series from quantile 
Previously arbitrary time series could be returned from `quantile`
depending on sort order for the last data point in the selected range.

Fix this by returning the calculated time series.

2ff0d595b0 app/vmselect/promql: add -search.disableCache flag for disabling response caching 
This may be useful for data back-filling, when the response caching
could interfere badly with newly added data points with timestamps
in the past.
