0eac538fc8 app/vmselect/promql: adjust the provided window only for range functions with dt in denominator
This should fix range function calculations such as `changes(m[d])` where `d` is smaller
than the scrape interval.

c05d443791 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.

f334908c22 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.

837e349b7d app/vmselect/promql: do not strip __name__ form time series after binary comparison operation
Example:

  foo > 10

Would leave `foo` name for all the matching time series on the left.

02417071cd README.md: use link to Wikipedia about broken gossip protocol instead of a link to document about Gossip protocol removal from Thanos
Thanos removed non-working gossip protocol a few months ago - https://github.com/improbable-eng/thanos/issues/734 ,
so the link to the design document https://github.com/improbable-eng/thanos/blob/master/docs/proposals/approved/201809_gossip-removal.md
became unavailable. So use a link to Wikipedia article instead.

Closes https://github.com/VictoriaMetrics/VictoriaMetrics/pull/68

28d9904efc lib/fs: panic with fatal error when directories cannot be removed
Unremoved directories may lead to inconsistent data directory,
so VictoriaMetrics will fail to start next time.

So panic on the first error when trying to remove directory in order
to simplify recover process.
