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: 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.
