Prometheus storage.tsdb.retention.time, scrape_interval and remote_write for low-traffic cost control

The configuration involves --storage.tsdb.retention.time for local pruning, a coarser scrape_interval to reduce head block series churn, and remote_write to a separate store. Drop relabeling is also u
