Brief overview: TO configure tracking percentile metrics in rainerscript: User would need to define: - which percentile to track, such as [p50, p99, etc.] - window size - note, this correlates directly with memory usage to track the percentiles. To track a value, user would call built-in function `percentile_observe()` in their configurations to record an integer value, and percentile metrics would be emitted every impstats interval.
