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.

README.md: add max_shards: 100
to the recommended Prometheus config
...
Prometheus establishes a connection per shard in remote_write config.
By default it establishes up to 1000 connections to remote storage (max_shards: 1000).
This is quite big, so set `max_shards: 100` in the recommmended Prometheus config.
