Add Adaptive Capacity Listener plugin descriptor

[hilalsidhic]

Description

Adds the descriptor for Adaptive Capacity Listener (adaptive-capacity-listener) to site/dat/repo/various.json.

Adaptive Capacity Listener is an Apache JMeter listener and backend monitor plugin designed for adaptive capacity and resilience testing. It continuously tracks response performance over configurable evaluation windows and automatically halts tests when configured degradation or SLA thresholds are breached, injecting a synthetic failure sample to clearly mark threshold breaches in summary reports and HTML dashboards.

Features

• Multi-Policy Degradation Evaluation:
  • PERCENT_LATENCY: Detects abnormal percentile latency growth compared to prior evaluation stages.
  • ABSOLUTE_LATENCY: Enforces a hard latency ceiling in milliseconds.
  • ERROR_RATE: Monitors error percentage per evaluation window.
  • ERROR_COUNT: Enforces a maximum acceptable error count per window.
• Headless & CLI Compatible: Operates both in JMeter GUI mode (under Add → Listener) and in headless/CLI mode via Backend Listener (AdaptiveCapacityBackendListener).

This overlaps with the existing Auto-Stop Listener (jpgc-autostop), which already stops a test on runtime KPIs — response time, latency and error rate thresholds, evaluated over a sustained-breach window: https://jmeter-plugins.org/wiki/AutoStop/

The criteria that Auto-Stop doesn't have — a per-window error count ceiling, and comparing a response time percentile against the previous window — would be welcome as a pull request to Auto-Stop itself. It lives in this repo at plugins/autostop/.
