## What is the purpose of the change This PR introduces a repeatable, Docker-based distributed Storm dev cluster designed for realistic benchmarking `storm-perf` on a local machine. It provisions a complete environment, including Nimbus, ZooKeeper, and two Supervisor, forcing inter-worker traffic across the network to trigger true serialization overhead. Backed by a full observability stack (Prometheus and Grafana), the setup provides granular, per-task tracking via Storm Metrics v2. Additionally, it includes a `netsim.sh` utility to inject controlled network latency and jitter, allowing developers to easily stress-test topology resilience and analyze bottlenecks under degraded network conditions. ## How was the change tested I verified the environment by executing the benchmark smoke test outlined in the README.md, running the `FileReadWordCountTopo` topology for 120 seconds across two workers on separate supervisors. Smoke testing successfully validated the baseline performance and the replication of bottlenecks. Injecting typical datacenter network conditions (3 ms latency, 1 ms jitter) caused average complete latency to rise from 390 ms to 446 ms; this induced back-pressure safely reduced total tuple throughput from 40.93M to 36.25M without dropping packets. -- This is an automated message from the Apache Git Service.
