The CreateAndConnectCfgDrive and DeleteVOpt tasks were passing the
instance into the task.Task init as the first argument. The first arg
for the Task init is actually the task name [1]. This means that those
task names were string representations of the instance which will cause
failures if there are any non-ascii characters. This corrects the Task
init calls by removing instance as the first argument. The name kwarg
is now being used throughout the PowerVM tasks to avoid similar issues
in the future.
