docs: Registers a flag whose value must be an integer.
  
    If lower_bound, or upper_bound are set, then this flag must be
    within the given range.
  
    Args:
      name: str, the flag name.
      default: int|str|None, the default value of the flag.
      help: str, the help message.
      lower_bound: int, min value of the flag.
      upper_bound: int, max value of the flag.
      flag_values: FlagValues, the FlagValues instance with which the flag will
          be registered. This should almost never need to be overridden.
      **args: dict, the extra keyword args that are passed to DEFINE.
