Provisioning downloaded every cloud image over SSH into
/var/lib/vz/template/netork-images, on the node's root filesystem. On a
small root that fills up and takes Proxmox down with it (netOrk #480).
When the node has an active storage with content type "import" (Proxmox
8.2+), Proxmox now does it itself: download-url with checksum
verification into that storage, then import-from as the root disk. The
file is named after a hash of the full URL and reused when present.
Proxmox takes the format from the extension and has no ".img", so
Ubuntu's qcow2 .img is stored as .qcow2 -- a wrong guess fails at import
instead of attaching a qcow2 container as a raw disk.
Without an import storage, or for an image type Proxmox cannot import,
the SSH download is used as before.
