Change subject: IMPALA-4187: Switch RPC latency metrics to histograms ...................................................................... IMPALA-4187: Switch RPC latency metrics to histograms It's usually better to measure latency distributions with histograms, not avg / min / max. This change switches out the metrics that measure the latency of RPC processing time to histograms. Add HistogramMetric::Reset() to allow histogram to remove all entries. Added spinlock around histogram access.
