Description

During the development of bundle examples and scripts, I realized that it's better to use lazy=True as default value in the ConfigParser to continuously load components. For example, actually we already use it in the run script:
https://github.com/Project-MONAI/MONAI/blob/dev/monai/bundle/scripts.py#L373
And here is another typical example code:

parser = ConfigParser()
parser.read_config(config_file)

# instantialize the components
model = parser.get_parsed_content("network")
model.load_state_dict(torch.load(ckpt_path))

dataloader = parser.get_parsed_content("dataloader")
inferer = parser.get_parsed_content("inferer")
postprocessing = parser.get_parsed_content("postprocessing")
