adds vendor and product information for SCSI devices to the json schema and
checks in the VM create/update API call if it is possible to add these to QEMU
as a device option
Signed-off-by: Hannes Duerr <h.du...@proxmox.com>
---
changes in v2:
- when calling the API to create/update a VM, check whether the devices
are "scsi-hd" or "scsi-cd" devices,where there is the option to add
vendor and product information, if not error out
- change the format in product_fmt and vendor_fmt to a pattern that only
allows 40 characters consisting of upper and lower case letters, numbers and
'-' and '_'.
