Filip Petkovski	6100e756a8	Ignore stale histograms for counter reset detection The histogram stats decoder keeps track of the last seen histogram sample in order to properly detect counter resets. We are seeing an issue where a histogram with UnknownResetHint gets treated as a counter reset when it follows a stale histogram sample. I believe that this is incorrect since stale samples should be completely ignored in PromQL. As a result, they should not be stored in the histogram stats iterator and the counter reset detection needs to be done against the last non-stale sample.

Filip Petkovski	6e68046c25	Implement histogram statistics decoder (#14097 ) Implement histogram statistics decoder This commit speeds up histogram_count and histogram_sum functions on native histograms. The idea is to have separate decoders which can be used by the engine to only read count/sum values from histogram objects. This should help with reducing allocations when decoding histograms, as well as with speeding up aggregations like sum since they will be done on floats and not on histogram objects.
