Regarding the disk metrics, Hyper-V cannot collect read_requests or
write_requests metrics as the other inspectors do, but it can collect
the disk IOPS instead. This patch is targeted to Windows
Hyper-V / Server 2012 R2, Windows 8.1 or newer, since they introduced
disk metrics collection in Hyper-V.
This patch adds iops metrics implementation in Hyper-V Inspector as
well as disk iops and per disk iops pollsters.
