feat: enhance S3 storage and improve Tailscale ACL sync

[jaxxstorm]

Important

Enhance S3 storage configuration, improve logging, and refine Tailscale ACL synchronization handling.

• S3 Storage Enhancements:
  • Added S3Endpoint and S3Region flags in CLI struct in main.go for custom S3 configurations.
  • Updated InitializeS3Client in state.go to handle custom S3 endpoints and regions, and to log parsed S3 configurations.
  • Modified saveToStorage and loadFromS3 in state.go to use ObjectKey for S3 operations.
• Logging Improvements:
  • Enhanced logging in state.go for S3 operations, including warnings for unrecognized storage configurations.
  • Improved debug logging in main.go for state changes and Tailscale operations.
• Tailscale ACL Sync:
  • Refactored Start and Push functions in sync.go to ensure proper logging and error handling during ACL synchronization.
  • Removed id fields from ACL JSON in sync.go using removeIDFields function.

More details

• Looked at 428 lines of code in 3 files
• Skipped 0 files when reviewing.
• Skipped posting 3 drafted comments based on config settings.

1. pkg/common/state.go:255

• Draft comment:

return nil, "", "", fmt.Errorf("storage URL must begin with s3://, got %q", storageURL)

• Reason this comment was not posted:
  Confidence changes required: 0%
  The error message in InitializeS3Client when the storage URL does not start with s3:// is clear and provides the expected format, which is good for debugging.

2. main.go:121

• Draft comment:

logger.Fatal("Invalid storage scheme. Must be file:// or s3://")

• Reason this comment was not posted:
  Confidence changes required: 0%
  The code in main.go sets up the S3 client and checks for valid storage schemes. It correctly handles the initialization of the S3 client and logs errors if the initialization fails. The logic for checking the storage scheme is clear and ensures that only valid schemes are used.

3. pkg/sync/sync.go:99

• Draft comment:

delete(val, "id")

• Reason this comment was not posted:
  Confidence changes required: 0%
  The function removeIDFields is designed to recursively remove "id" fields from a map. It correctly handles different types of data structures, such as arrays and maps, and returns the modified object. The logic is clear and concise.
