* Remove experimental out-of-order native histogram flag This feature has been available in Prometheus since September 2024, and has no known issues. Therefore proposing to remove the flag entirely and always have it on. Note that there are still two settings that need to be configured (out-of-order time window > 0 and native histograms enabled) for this feature to work.
