This patch adds a new output plugin that sends logs to ArvanCloud CloudLogs
service. The plugin supports:
- GZIP compression
- Configurable timestamp formats
- Custom log fields mapping
- Retry logic and error handling

The plugin has been tested with ArvanCloud CloudLogs API and successfully
delivers logs with proper formatting and timestamps.
