Need to support vSphere dependent disk/independent disk

For vsphere, we need to support to build/change disk between dependent and independent

This is the standard virtual disk configured out of the box. When a snapshot is in use, this disk is included in the snapshot. This is not the case for independent disks . You can see and change the disk mode via the vSphere Web client (via vCenter Server)

We need allow user to build VM with dependent/independent mode
We also need to allow user to change the disk mode in day 2

Example/Use case(s):
To build VM, allow select disk mode dependent/independent
Day2, select one disk. change disk mode
VM must be powered off to do so.

Closing as this is a duplicate of this request
