CopyKeys - Does not detect VM with encryption because VM extension name is hardcoded

[o-l-a-v]

The CopyKeys script does not detect a VM with encryption because it checks for the VM encryption extension with a hardcoded name.

Hardcoded extension name:

• published-scripts/CopyKeys/CopyKeys.ps1

  Line 315 in 0d1520c

  static [string] $adeExtensionPrefix = "azurediskencryption"

Check for eligible VM:

• published-scripts/CopyKeys/CopyKeys.ps1

  Lines 597 to 606 in 0d1520c

  	foreach ($Item in $VmList)
  	{
  	if (($null -ne $Item.Extensions -and $Item.Extensions.Count -gt 0) -and
  	($Item.Extensions.Id | ForEach-Object { `
  	$_.split('/')[-1].tolower().contains( `
  	[ConstantStrings]::adeExtensionPrefix)}) -contains $true)
  	{
  	$SuppressOutput = $VmListBox.Items.Add($Item.Name)
  	}
  	}
