=== Testing packaging on Windows

The packaging tests also support Windows Server 2012R2 and Windows Server 2016.
Unfortunately we're not able to provide boxes for them in open source use
because of licensing issues. Any Virtualbox image that has WinRM and Powershell
enabled for remote users should work.
