Make config file a positional argument, as it is required

Browse source 
- Test invalid config file path throws. Remove redundant cli test

- Simplify cli parser code
  - Do not need to explicitly check if args.config_file set.
    argparser checks for positional arguments automatically

- Use standard semantics for cli args
  - All positional args are required. Non positional args are optional

- Improve command line --help description
