Summary of Changes

Hello, 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 primarily focuses on preparing for the v1.85.0 release by updating various internal and external dependencies, enhancing the toolkit's dependency management system, and introducing new features for Google Cloud Storage. It also includes improvements to Slurm topology generation, GKE cluster configurations, and overall test suite robustness, ensuring a more stable and feature-rich toolkit.

Highlights

• Automated Dependency Management: Introduced a new system for automatically downloading and managing terraform and packer binaries, including version pinning and checksum verification. This simplifies setup and ensures consistent tool versions across environments.
• Version Update: The toolkit's version has been updated to v1.85.0 across the codebase, including the main CLI, Terraform module metadata, and various Python package dependencies.
• Enhanced GCS Bucket Functionality: Added support for the RAPID storage class and placement_zones in Google Cloud Storage buckets, enabling high-performance zonal storage and Anywhere Cache integration. A new example blueprint rapid-storage-slurm.yaml demonstrates this feature.
• Improved Slurm Topology Generation: Refined the Slurm topology generation logic to include unique block UUIDs and added comprehensive docstrings for better clarity and maintainability.
• GKE Cluster DNS Configuration Update: Changed the default cluster_dns provider for GKE clusters from PROVIDER_UNSPECIFIED to KUBE_DNS.
• Terraform Provider Version Range Update: Updated the supported version range for Google and Google-beta Terraform providers to >= 6.9.0, <= 7.23.0.
• Robustness Improvements in Daily Tests: Added the --robust flag to gcluster destroy commands in daily integration tests, enhancing the reliability of cleanup operations.
