function relocateCIVMsOnDisabledDatastores {
  <#
  .SYNOPSIS
    Returns all vCD VMs on specified datastore(s)
  .DESCRIPTION
    This function is for migrating vCloud Director (vCD) VMs for a specific use case.  The relocate method will be called on all VMs.  If the VM is on a disabled datastore, the VM will be relocated to an enabled datastore.  Since relocating the VM possibly fail, you can alternatively specify a datastore that the VM will be storage vMotioned to. 
    Tested with vCD 5.5 / vCenter 5.5
