History
beorn7 7f30b0984d Implement isolation 
This has been ported from https://github.com/prometheus/tsdb/pull/306.

Original implementation by @brian-brazil, explained in detail in the
2nd half of this talk:
https://promcon.io/2017-munich/talks/staleness-in-prometheus-2-0/

The implementation was then processed by @gouthamve into the PR linked
above. Relevant slide deck:
