  Azure VM - We are not getting power state
  The VM data we are getting back does not tell you if the VM is running or not.
  
  I think perhaps you have to tell the `list_all` api what you want - we want `instanceview`
  
  https://docs.microsoft.com/en-us/rest/api/compute/virtualmachines/instanceview
  
  Not sure how this happens via SDK.
