salt-cloud vsphere vsan virtual machine creation failure

Description of Issue/Question

When attempting to create a VM on vCenter 6.5 using Salt Cloud on a VSAN, the creation fails. When applying the same configuration to local ESXI storage, the VM is created.

Setup

(Please provide relevant configs and/or SLS files (Be sure to remove sensitive info).)

Start with salt/cloud/clouds/vmware.py around create and salt/utils/vmware.py around wait_for_task, then reproduce the supplied configuration against VSAN and local ESXi storage. Compare the task and error paths; done means the reported VSAN configuration creates the VM successfully without the CannotCreateFile failure.
