app/vmselect/promql: add deriv_fast function for calculating fast derivative
...
`deriv_fast` calculates derivative based on the first and the last point on the interval
instead of calculating linear regression based on all the data points on the interval.

app/vmselect/promql: ajdust data model to the model used in Prometheus
...
Do not take into account data points on the range `[timestamp .. timestamp+step)`
when calculating value on the given `timestamp`.
Use only data points from the past when performing these calculations like Prometheus does.
This should reduce discrepancies between results returned by VictoriaMetrics
and results returned by Prometheus.
