Fix: Handle 403 Forbidden in get_reservation_details for shared reservation

[kvenkatachala333]

I have modified the Slurm util.py script to gracefully handle permission errors when fetching reservation details. This allows the integration to support shared reservations where the service account does not have compute.reservations.get permission on the host project.

Summary of Changes

Hello @kvenkatachala333, 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 introduces robust error handling within the Slurm utility script to manage 403 Forbidden responses when fetching Google Cloud reservation details. By catching these specific permission errors, the system can now gracefully proceed with minimal reservation information, thereby extending support for shared reservations where the service account might not have full access to the host project's compute resources.

Highlights

• Error Handling for Reservations: Implemented a try-except block in the get_reservation_details function to gracefully handle HttpError exceptions that may occur during API calls.
• 403 Forbidden Graceful Degradation: Specifically catches 403 Forbidden errors, logs a warning, and returns a ReservationDetails object with minimal settings instead of raising an exception, allowing the system to continue operation.
• Shared Reservation Support: Enables support for shared reservations where the service account might lack compute.reservations.get permission on the host project, by providing a fallback mechanism.

Code Review

This pull request introduces a fix to gracefully handle 403 Forbidden errors when fetching reservation details, which is particularly useful for shared reservations. The implementation correctly uses a try-except block to catch HttpError, checks for the 403 status, and returns a default ReservationDetails object while logging a warning. This is a good approach. My main feedback is regarding the lack of unit tests for this new error handling logic, which is important for ensuring long-term maintainability and correctness as per the project's contribution guidelines.
