Create a Parser class that uses multiple SectionParser interfaces to handle parsing the different sections of an init rc. Create an ActionParser and ServiceParser that implement SectionParser and parse the sections corresponding to Action and Service classes. Remove the legacy keyword structure and replace it with std::map's that map keyword -> (minimum args, maximum args, function pointer) for Commands and Service Options. Create an ImportParser that implements SectionParser and handles the import 'section'. Clean up the unsafe memory handling of the Action class by using std::unique_ptr.
