Bootiful OpenTelemetry

" summary

Demonstrates instrumenting a Spring Boot microservice demo (front-end, anti‑fraud, checkout with Postgres and Redis) using the OpenTelemetry Java agent that ships traces and metrics to an OpenTelemetry Collector via OTLP. Generates ~100 transactions/min with a chaos monkey to show failures, visualizes per-request traces, attached logs (logs support is draft), and adds manual attributes like customer_id and order_sum. Discusses sampling overhead and recommends combining auto and manual instrumentation and considering tail-based sampling for storage cost control.
