…ution

- Introduced a new `priority` field in the User model to manage user priorities for scheduling and rate limiting.
- Updated the IdentityAccessManager to handle user priority during user creation and updates.
- Enhanced the BaseModelRouter to implement a least-loaded routing strategy for model invocation, selecting the provider with the fewest inflight requests.
- Added Celery configuration for asynchronous task execution, allowing model invocations to be processed in the background.
- Implemented a new `invoke_model_request` function to handle both eager and Celery-based invocations based on configuration.
- Updated API schemas to include priority in user-related requests and responses.
- Added necessary database migrations to support the new priority field in the User table.
- Enhanced unit tests to cover new functionality and ensure proper integration with Celery.
