.IO limits added to the Windows Guest debugging tool
With this update, you can view IO limit values directly from the Windows Guest debugging tool, streamlining the troubleshooting process for IO errors related to Windows Failover Cluster. This enhancement automates the process of capturing IO limit values, reducing manual effort and improving efficiency, especially for LUN type disks (SG_IO).

This feature provides a similar functionality to that of SCSI Pass-Through Interface (SPTI) API, making troubleshooting more efficient.

As a Support Engineer, I need the IO limit values as seen from inside the Windows Guest to more easily troubleshoot IOErrors related to Windows Failover Cluster. The host values are captured on the sosreport of the hypervisor, but for Windows its always a manual task.

Able to see the IO limits after running the tool from RHEL-1472, similarly to captured by spti.exe in https://github.com/microsoft/Windows-driver-samples/blob/main/storage/tools/spti/src/spti.c#L844
Only needed for LUN type disks (SG_IO)
