Explain cluster restoration

[tbouska]

Proxmox makes it easy to destroy the cluster and rebuild it. There are still some manual post-install steps though:

1. Create Longhorn volumes from backup:

• hass-config, 5Gi
• linkace-db, 512 Mi
• monica-config, 1 Gi
• monica-db, 10 Gi
• qbittorrent-config, 15 Gi
• gaps-config, 15Gi
• bazarr-config, 15Gi
• prowlarr-config, 1Gi
• nzbget-config, 1Gi
• radarr-config, 15Gi
• lidarr-config, 10Gi
• sonarr-config, 10Gi
• overseerr-config, 1Gi

2. Create buckets in thanos minio tenant: thanos, loki

Unfortunately, Longhorn related tasks can't be automated yet: longhorn/longhorn#613

Minio buckets creation can't be automated too: https://docs.min.io/minio/k8s/reference/minio-kubectl-plugin.html

I tried listing the buckets in the helmrelease and hoped for their creation at tenant initialization, but it failed. It appears I have to pass the console user credentials, but I found no working way how to do that.
