New Attach/Detach data disks APIs support for VMs and VMSS

[alexn-orca]

On the 18th of October Azure introduced the new APIs for attaching and detaching data disks for VMs and VMSS.

I would like to have wrappers on those APIs available in Azure python SDK, to me able to attach/detach data volumes without calling update VM operation.

Currently I do this:

    data_disk_update = (virtual_machine.storage_profile.data_disks or []) + [  # type: ignore
        {
            "lun": len(virtual_machine.storage_profile.data_disks),  # type: ignore  # can be 0-15
            # 'name': volume['name'],
            "create_option": DiskCreateOption.attach,
            "managed_disk": {"id": volume_id},
        }
    ]
    virtual_machine_update = {"storage_profile": {"data_disks": data_disk_update}}
  async_disk_attach = await compute_client.virtual_machines.begin_update(rg_name, vm_name, )
  await async_disk_attach.result()

What I want to be able to do:
async_disk_attach = await compute_client.virtual_machines.attach_volume(rg_name, vm_name, volumes)
