Add CSV Export of Detailed Request Logs

[Kobiwizards]

Prerequisites

• I am using the latest version of Locust
• I am suggesting a new feature, not asking a question

Description

Title: Add CSV export functionality for per-request detailed logs

Description: Current CSV exports provide aggregated statistics only. For deep analysis, users need per-request data including timestamps, response times, and success/failure status. This feature would add:

--csv-requests flag to export per-request logs

CSV columns: timestamp, method, name, response_time, status_code, content_length, failure_reason

Optional: include custom request metadata

Automatic file rotation for long-running tests

Files to modify: locust/stats.py, locust/event.py, locust/argument_parser.py, locust/main.py

This is a good idea. I think it could be implented as a simple request hook, perhaps listed under contrib folder. If you can write it, I'd love to see a PR
