Title: make config parsing better

If tron is unable to actualize the node_pool, it'll not have the property defined at all (as opposed to having it defined and set to None). Then you get the COMPLETELY FRACKING USELESS error message `AttributeError: 'Action' object has no attribute 'node_pool'`, which is moderately hard to debug.
