New features

• Opt-in export of audit logs to S3, Azure Blob or Google Cloud Storage
• Newline-delimited JSON written to a dedicated logs/audit/ folder, partitioned by day
• Incremental and runs in the background off the audit log hot path, with a single exporter under high availability
• Exported files are never deleted from object storage, so database retention can be set much lower
• Recommended setup to forward audit logs to a SIEM for long-term security analysis
