title: Get-azureRmDisk does not show property DiskState
body: <p>I need to get property like "DiskState", I am using cmd-let Get-AzureRMdisk, and what I got:
  1) from my laptop, using <code>connect-azurermaccount</code> then <code>get-azurermdisk</code>, doesnt give expected property 2) I tried from Automatio account, created a runbook and then paste my code there, the same, I got more values but didn't get "diskstate" value 3) I see that I can get it from Azure Cloud Shell console. I would like to get this value from a script running as a runbook. Moreover I tried to use command like --> <code>Get-AzureRmDisk | Where-Object ManagedBy -ne $null</code>, but didnt get any interesting results. Is there any matheto do get this mentioned property "diskstate" using powershell runbook from Automation account? </p>
