Prometheus and PromQL: Scrape or Push, rate, histogram_quantile, Recording Rules and Native Histograms

With Bookstore's metrics we work through rate, increase, histogram_quantile and error-rate queries, name translation and recording rules, and measure how accurate percentiles are with classic buckets versus native histograms.
