[PR-716]: Improve Handling for PAT and USER_ID

[srikanthbachala20]

This pull request refactors the authentication and logging mechanisms in the Clarifai CLI to improve maintainability and user feedback. The key changes include replacing the validate_pat_token function with validate_context_auth, introducing structured logging via the logger module, and enhancing error handling and user feedback.

Authentication Refactor:

• Replaced validate_pat_token with validate_context_auth for validating context credentials, consolidating the logic and improving clarity. (clarifai/cli/base.py, clarifai/utils/cli.py) [1] [2]
• Updated the validate_context_auth function to use structured logging for success and error messages, replacing return values with sys.exit(1) for invalid credentials. (clarifai/utils/cli.py)

Logging Enhancements:

• Replaced print statements with logger.info and logger.error across the CLI commands to standardize logging and improve debugging. (clarifai/cli/base.py, clarifai/cli/model.py) [1] [2] [3] [4]
• Added logger import to relevant files for consistent logging usage. (clarifai/utils/cli.py)

Error Handling Improvements:

• Enhanced error messages for invalid user IDs and missing PATs in the local_runner function, ensuring clear user guidance and proper exits. (clarifai/cli/model.py)
• Improved error feedback in validate_context_auth for common issues like invalid tokens, SSL errors, and network problems. (clarifai/utils/cli.py)

Pull Request Overview

This PR refactors the Clarifai CLI’s authentication and logging to consolidate credential validation, standardize output via a logger, and improve user feedback and exit behavior.

• Consolidates PAT validation by replacing validate_pat_token with validate_context_auth and shifting from return values to structured logging and sys.exit.
• Replaces print statements with logger.info/logger.error across commands for consistent logging.
• Enhances error handling in local_runner and login/create commands to clearly log missing or invalid credentials before exiting.

• Update the function signature and docstring of validate_context_auth to reflect that it no longer returns a tuple but exits directly. Consider using -> NoReturn and removing or revising the Returns section.

def validate_context_auth(pat: str, user_id: str, api_base: str = None) -> Tuple[bool, str]:

clarifai/cli/model.py:475

• The logger is used here but not imported in this module; add from clarifai.utils.logging import logger at the top of the file.

    logger.info(f"Current user_id: {user_id}")
