These are client-only changes that make two aspects of its configuration that so far could only happen via command line flags handled uniformly: the controller to connect to, and the verbosity level.
This also permits simpler cluster config .ini files: in configs where agents connect to the controller, it will often be the case that the instances section is simply a list of instance names that is already expressed via the names of instances that nodes declare themselves running on. You can now omit the instance section in that case, allowing nodes to imply the instances list.
