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 introduces a new quickstart sample for the Google Cloud Storage Node.js client library, along with its associated system tests and supporting infrastructure. The primary goal is to provide a clear, executable example for users to quickly understand and implement basic Google Cloud Storage operations, specifically bucket creation, while ensuring testability and proper resource cleanup.

Highlights

• New storage directory: A dedicated directory for Google Cloud Storage samples has been introduced, containing its own package.json and related files.
• Quickstart sample for Cloud Storage: A quickstart.js file was added, demonstrating how to create a Google Cloud Storage bucket using the Node.js client library.
• System tests for quickstart: Corresponding system tests (quickstart.test.js) were implemented to verify the functionality of the quickstart sample.
• Cleanup script: A cleanup script was added to programmatically remove test resources, specifically buckets created during testing, ensuring a clean environment.
• Sample resources: Various text files and a .gitignore were added under storage/resources to support the samples and their testing.

Code Review

This pull request migrates the storage quickstart sample and its tests. The changes look good overall, but I have a few suggestions to improve the code's clarity, efficiency, and robustness.

In quickstart.js, I've suggested refactoring the main function to use async/await directly, which simplifies the code.
For the cleanup script, I found the bucket deletion logic to be complex and inefficient. I've proposed a much simpler and more performant implementation using Promise.all and bucket.delete({ force: true }).
Finally, in the test file, I've recommended a small change to make the cleanup hook more robust.

Please take a look at my detailed comments.
