docs: // ParentFromPath takes a relative object path (usually a folder), an
  // object type, and an optional supplied datacenter, and returns the parent

  // The datacenter supplied in dc cannot be nil if the folder type supplied by
  // ft is something else other than VSphereFolderTypeDatacenter.
