VMHyperV: Add support for VM version # for Win10 and Server 2016

[MS-MatthewWalker]

New parameter available for VM creation is version #, this allows for creation of a VM on Win10 or higher that is backwards compatible with previous.

Valid versions: 5 for Windows 8, 8.1 Server 2012 and 2012 R2 6 for Windows 10 6.2 for Windows 10 TH2 7.0 for Windows Server 2016 TP5 -

I think those are correct, might have some off and other versions may exist or be available at later time

@MS-MatthewWalker I see v7.1 on Server 2016 TP5
