Add tunnelling to allow querying Cloud Backup snapshots
The Legacy Backups have a feature to allow connecting (tunnelling) to a snapshot to query it. This allows querying a database snapshot which is great for quickly inspecting data in the past for troubleshooting. This would be handy to have for the Cloud Backups. With Cloud Backups instead I now have to download a snapshot, load it temporarily on a cluster and remove it when done.
We are planning on building a new version of queryable for Cloud Backup but not with a tunnel. In the meantime, I would suggest provisioning a new cluster, restoring the backup, do what you need, and then tear it down. Cloud Backup restores are extremely fast. This would be the best way for the time being.
