Speed up BenchmarkPostings_Stats (#9213) 
The previous code re-used series IDs 1-1000 many times over, so a lot
of time was spent ensuring the lists of series were in ascending order.
The intended use of `MemPostings.Add()` is that all series IDs are
unique, and changing the benchmark to do this lets it finish ten times
faster.

(It doesn't affect the benchmark result, just the setup code)

This directory contains the Prometheus storage layer that is used in its 2.x releases.

A writeup of its design can be found here.

Based on the Gorilla TSDB white papers.
