Description of problem: On CFME, for RHV, VM Reconfigure->Disk delete action, removes the disk from VM (disk detached), and there is a missing option to remove the disk permanently.

Adding doc text, and this new CFME/RHV UI flag should be documented. Also same flag exist for CFME/VMWare, and should be documented as well.

Verified on CFME-5.8.0.13/RHV-4.1.1.8: For a down VM with 2 disks: Delete 1 disk with Delete Backing: Off => This disk was detached Delete 1 disk with Delete Backing: On => This disk was removed For an up VM with 2 disks: Delete 1 disk with Delete Backing: Off => This disk was detached Delete 1 disk with Delete Backing: On => Operation failed, as expected - when VM is down, it is not possible to remove the disk in a single REST API operation.
