Improve openai class

[luv-bansal]

This pull request introduces significant enhancements to the OpenAI-compatible API server implementation, including code refactoring, new utility methods, and improved error handling. The changes streamline request processing, add modularity, and simplify parameter extraction and validation. Minor updates include type cleanup and debugging code removal.

Enhancements to OpenAI-compatible API server:

• Refactored request parameter handling:

  • Introduced _extract_request_params to centralize and validate parameter extraction from request data. This reduces redundancy across methods.
  • Added _create_completion_args to construct completion arguments dynamically, improving flexibility for both streaming and non-streaming requests.

• Improved error handling:

  • Added _format_error_response to generate OpenAI-compatible error responses in a structured JSON format.

• Simplified request processing:

  • Updated _process_request and _process_streaming_request to use **kwargs and leverage the new helper methods for argument preparation. This reduces boilerplate code and enhances maintainability.

• Class initialization updates:

  • Replaced load_model with __init__ to initialize the OpenAI client and model more effectively. Added get_model as an abstract method for subclasses to specify the model name.

Code cleanup and minor updates:

• Type cleanup:

  • Removed unused imports (Optional, List) in clarifai/runners/models/openai_class.py.

• Debugging code removal:

  • Removed unnecessary debug print statements in async def main() in clarifai/runners/utils/code_script.py.

• String handling adjustment:

  • Updated _parse_default_value to return raw strings for STR data types instead of using repr, ensuring consistent handling of string defaults.
