What this PR does
A remote read request executed in SAMPLES mode can return samples outside of the queried range. The reason is that, for performance reasons, in Mimir we don't have a strong guarantee that samples outside the queried time range are filtered out by the
Queryable; at the end, PromQL engine will do it anyway. However, in a remote read request we may save on same returned data by filtering out samples out of the queried time range, which is what I'm proposing in this PR.Which issue(s) this PR fixes or relates to
