Remove 4 interval staleness heuristic. (#3244)
This means that if there is no stale marker, only the usual staleness delta (5m) applies. It has occured to me that there is an oddity in the heurestic. It works fine as long as you have 2 points within the last 5m, but breaks down when the time window advances to the point where you have just 1 point. Consider you had points at t=0 and t=10. With the heurestic it goes stale at t=51, up until t=300. However from t=301 until t=310 we only see the t=10 point and the series comes back to life. That is not desirable. I don't see a way to keep this form of heurestic working given this issue, so thus I'm removing it. |

Consider a series stale after 4.1 intervals with no data.
To cover the cases where stale markers may not be available, we need to infer the interval and mark series stale based on that. As we're lacking stale markers this is less accurate, however it should be good enough for these cases. We need 4 intervals as if say we had data at t=0 and t=10, coming via federation. The next data point should be at t=20 however it could take up to t=30 for it actually to be ingested, t=40 for it to be scraped via federation and t=50 for it to be ingested. We then add 10% on to that for slack, as we do elsewhere. |

Add initial staleness handing to promql.
For instant vectors, if "stale" is the newest sample ignore the timeseries. For range vectors, filter out "stale" samples. Make it possible to inject "stale" samples in promql tests. |
