* Card ID: CCT-676
* Backport to 1.31 branch
* When VM is created as Generation 2 in the setup wizard of
Hyper-V hypervisor, then hypervisor reports UUID of given
VM using little-endian. Thus it is not necessary to
convert this UUID as we do for Generation 1.
* We solve this issue by extending SQL query. We also ask
for VirtualSystemSubType, which contains version of VM
generation ("Microsoft:Hyper-V:SubType:1" or
"Microsoft:Hyper-V:SubType:2"). When VM is generation 1,
then we convert UUID from big-endian to little-endian
as we have did it in the past. When generation is 2, then
we do nothing with guest UUID.
* Changed code around little bit, because there was variable
uuid used for different purpose and it was confusing.
* TODO: hyperv.py deserves more refactoring
* More information about generation 1 or 2 on Hyper-V could be
found e.g. here:
