CRI integration test for Windows Device mounts
This test takes advantage of the fact that when you tell Windows to mount the GUID_DEVINTERFACE_DISPLAY_ADAPTER class, it will also mount the host's device store into the container, even if there is no real GPU on the host. Signed-off-by: Paul "TBBle" Hampson <[email protected]>
