If a storage of that type and name already exists (LVM, zpool, ...) but we do not have a Proxmox VE Storage config for it, it is possible that the creation will fail midway due to checks done by the underlying storage layer itself. This in turn can lead to disks that are already partitioned. Users would need to clean this up themselves. By adding checks early on, not only checking against the PVE storage config, but against the actual storage type itself, we can die early enough, before we touch any disk. For ZFS, the logic to gather pool data is moved into its own function to be called from the index API endpoint and the check in the create endpoint.
