Introduce a cluster setting `kv.range_split.load_reset_duration` which resets the load based splitter sampling after the set duration. When the set duration is zero, the load based splitter continues to only be reset when the per-second load falls below the load split threshold. This setting may be useful when a range services a non-stationary load distribution, such that the initially sampled set of split keys are unsuitable to determine a split key from (e.g., all the same key) but a later sample set is suitable.
