Ability to configure storageClass to attach disks to virtio instead of scsi bus on proxmox.

A new configuration could be like this

storageClass:
  - name: proxmox-fast-xfs
    storage: fast
    reclaimPolicy: Delete
    fstype: xfs
    bus: virtio

Thanks!

Hi, @kowalski7cc can you share details, why you use virtio agains VirtIO SCSI single ?

Thanks.

Your comment made me doubt about my choice of virtio, and so after some websearch I found the following pages:

• https://forum.proxmox.com/threads/virtio-block-still-first-choice-for-disk-performance.119111/
• https://forum.proxmox.com/threads/virtio-vs-scsi.52893/
• https://pve.proxmox.com/wiki/Performance_Tweaks

Which sometimes are a bit confusing on wich VirtIO block and VirtIO SCSI seems to be faster. I'd expect to be vio block because a slimmer stack, but they state SCSI one it's better mantained.
