Summary of Changes

Hello @HenryHengZJ, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the application's configurability by introducing a wide array of new command-line arguments. These additions allow for more detailed control over various system components, including authentication, enterprise features, metrics, proxy settings, and document loaders, alongside improvements to logging and database configurations. The changes aim to provide greater flexibility and customization for deployment and operation.

Highlights

• Expanded Configuration Options: Numerous new command-line arguments (flags) have been introduced to BaseCommand to provide more granular control over various aspects of the application.
• Categorization of Flags: Existing and newly added flags are now logically grouped under categories such as 'General Settings', 'Logging', 'Database', 'Auth', 'Enterprise', 'Metrics', 'Proxy', and 'Document Loaders' for improved organization and readability.
• New Functional Areas Configured: New configuration options have been added for authentication settings (SMTP, JWT), enterprise features (licensing, offline mode), metrics collection (Posthog, OpenTelemetry), proxy settings, and document loader paths (Puppeteer, Playwright).
• Enhanced Logging and Database Flags: Additional flags for logging (e.g., LOG_SANITIZE_BODY_FIELDS) and database connection (e.g., DATABASE_REJECT_UNAUTHORIZED) have been included to offer more control over these critical components.

Code Review

This pull request adds a significant number of new command-line flags for configuring the application. The flags are well-organized into logical groups using comments, which improves the readability of the BaseCommand class. The core change is sound, but I've identified an opportunity to improve the maintainability of the code that processes these flags. My review includes a suggestion to refactor the repetitive blocks of if statements into a single loop, which would make the code more concise and easier to manage in the future.
