Trainer.add_argparse_args not recognizing type

[kunshouout]

🐛 Bug

Following the guide, I added trainer args into the parser:

  parser = Trainer.add_argparse_args(parser)
   trainer = Trainer.from_argparse_args(args)

$ python main.py --gpus 1 --max_epochs 64 --arbitrary_trainer_arg some_value

Then I got error:
TypeError: 'str' object cannot be interpreted as an integer

It's because max_epochs is "str" rather than "int". I think an easy fix would be adding type-info in parser.add_argument in Trainer.add_argparse_args.
