These changes remove the use of discover.Config which was used to pass the driver root and the nvidiaCTK path in some cases. Instead, the nvidiaCTKPath is resolved at the begining of runtime invocation to ensure that this is valid at all points where it is used. Signed-off-by: Evan Lezar <elezar@nvidia.com>
