Maybe we can introduce a special permission called

Datastore.ReplaceDisk

That would allow the user to:

- allocate and upload a temporary disk with same size as 
  a existing one

- automatically replace the VM disk when upload completes

If the user has Datastore.AllocateSpace, we can use the 
unusedX volume mechanism (no need to auto-replace an existing disk)
