Establish unified way of passing controller parameters from either input file or as dictionary

[misi9170]

• Follow the paradigm in BatteryController
• Create some kind of input checker; possibly use attrs?

controller_parameters dict has been enabled on the HydrogenPlantController in #52, but still would like a more streamlined way (possibly on ControllerBase) of handling input controller_parameters.

Consider providing from input_file only via the interface; that is, controllers do not themselves need to accept the input dictionary (from Hercules or elsewhere).
