Is your feature request related to a problem? Please describe.
In some cases we might want to load partial models. this can be done by loading a state_dict with argument strict=False as per: https://pytorch.org/tutorials/beginner/saving_loading_models.html#warmstarting-model-using-parameters-from-a-different-model

Describe the solution you'd like
Allow users to pass kwargs to ignite's Checkpoint handlers as per: https://pytorch.org/ignite/handlers.html#ignite.handlers.Checkpoint.load_objects

Describe alternatives you've considered
None, as MONAI does not allow alternatives besides using Ignite directly.
