Automate restoring Home Assistant backups to test server

[ScottG489]

The existing Ansible playbooks are capable of getting a fresh VM HAOS install running on a new host. However, setting up the instance and restoring a backup is still manual and takes a while to wait for large backups to download, upload, and restore.

We should automate the backup restore process by downloading them from the local prod instance (or from the remote backup location, but that would be slower), then restoring them to the new instance. This should be possible using the HA API.
