Implement Subscription-Based User Management with Feature Authorization and Rate Limiting

[RanitManik]

Implement a system for managing users based on subscription plans. This system should include:

1. Subscription Management: Allow users to subscribe to different plans with varying features.
2. Feature Authorization: Ensure that users can only access features associated with their subscription level.
3. Rate Limiting: Apply limits on how often users can access certain features to prevent abuse and ensure fair usage.
