test: add more context to cleanup error messages

[Camila-B]

Currently, when an error occurs during cleanup, no context may be given as to what led to the error. Ex. ERROR: [CLEANUP] Failed to clean test environment: rpc error: code = Internal desc = Internal error encountered.

Summary of Changes

Hello @Camila-B, 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 focuses on enhancing the diagnostic capabilities of the test environment cleanup routine. By wrapping existing errors with more descriptive messages, the changes aim to provide clearer feedback when cleanup operations fail, thereby streamlining the debugging process and improving the overall reliability of test runs.

Highlights

• Enhanced Error Context: Error messages during the test environment cleanup process have been significantly improved by adding specific context to each potential failure point. This change makes it much easier to identify the exact step that failed.
• Improved Debuggability: The previous generic error returns (e.g., return err) have been replaced with formatted error messages (e.g., return fmt.Errorf("failed to do X: %v", err)), providing immediate insight into the cause of a cleanup failure.

Code Review

This pull request improves error handling in the test cleanup process by wrapping errors with fmt.Errorf to provide more context. The changes are straightforward and correct. I've added a couple of minor suggestions to fix a typo and improve code consistency.

[gemini-code-assist]

For consistency with other error messages in this function (e.g., line 98), it's better to use double-quoted strings for fmt.Errorf format strings instead of raw string literals, as there are no special characters that need escaping. This applies to other fmt.Errorf calls in this function as well.

Suggested change

	return fmt.Errorf(`failed to check reconciler-manager status: %v`, err)
	return fmt.Errorf("failed to check reconciler-manager status: %v", err)

[tiffanny29631]

My feeling is the error happens around watching the deployments to be available. See https://oss.gprow.dev/view/gcs/oss-prow-build-kpt-config-sync/logs/kpt-config-sync-autopilot-rapid/2009550871913828352.

[tiffanny29631]

Agree that we can add this change first to get more context. The API server might be unstable in Autopilot.
