Hi@gryczj and reviewers,

I'm currently reviewing this pull request and will post my detailed review in a few minutes. In the meantime, here's a quick summary to help everyone get up to speed:

This pull request adds functionality for managing Compute Engine snapshot schedules. Specifically, it introduces three new JavaScript samples:

• createSnapshotSchedule.js: Creates a new snapshot schedule with customizable settings (daily, weekly, or monthly; retention policy; labels).
• attachSnapshotSchedule.js: Attaches an existing snapshot schedule to a Compute Engine disk.
• deleteSnapshotSchedule.js: Deletes a snapshot schedule. Note that this will fail if the schedule is attached to a disk.

Each sample includes comprehensive comments and error handling. Unit tests are also provided inattachSnapshotSchedule.test.js to verify the functionality.

The intent is to provide developers with clear, concise examples for working with Compute Engine snapshot schedules using the Node.js client library. This enhances the documentation and makes it easier for users to automate disk snapshots.

And now, a little haiku to lighten the mood:

Code flows like a stream,
Tests run, bugs swim downstream,
Clean code shines so bright.

Looking forward to the discussion!
