[libvirt] [PATCH v2 04/10] hyperv: add hypervWqlQuery struct.
Since this is the last commit that will compile in the series, the
remaining patches should be squashed into this one - they are kept
separate only for code review purposes.
This struct is to be passed to enumerate-and-pull wsman request (to run
"Select" queries) and provides the hypervWmiClassInfoListPtr instance
from which we can extract the version specific info using the new
hypervGetWmiClassInfo function (currently unused)
