Description
Updates the snapshot restore endpoint to send progress updates to the frontend.
Similar to creating a snapshot, adds a job to the queue for restoring data from the snapshot id requested by the user. Does this asynchronously by default so that the GUI remains unblocked, and the user can continue to navigate through the application while the restore task is running.
Returns regular status updates of the job in progress as well as the final results of all successful and failed writes.
