Bug description:
  Comment from @dims on code review -
  https://review.openstack.org/#/c/37819/

  "Shawn, i was going through the code again for this change and
  realized that when *not* using linked clone we don't the vmware_base
  dir at all which means we do a fresh transfer of image from glance to
  hyper every time. Would it be better to still have the vmdk in
  vmware_base and do a CopyDatastoreFile_Task or CopyVirtualDisk_Task to
  copy it over into the new directory from vmware_base for each new
  guest? In other words, we always cache vmdk(s) in vmware_base to skip
  the network transfer (and hence take the network transfer hit just one
  for the first time an image is needed in a hyper)"

  Response from Shawn:
  I was dealing with a test related issue. That I finally resolved by re-introducing some "bad" code, comments are in line with the code. Can you see clear to view that change as out of scope of this patch? That feels like a separate issue from introducing new controls. I would prefer to open a separate bug for this since the feature to turn *off* linked-clone strategy was already present (as a global setting).
