Is your feature request related to a problem? Please describe.
save_best_only is a special case of save_top_k. However, save_tok_k checkpoints can be used to create ensemble model during the test time.

Describe the solution you'd like
keep a dict of {epoch: monitor} of length k, and save new ckeckpoint that can enter this dict, remove the worst checkpoint.

Hi, I have some questions.

I noticed save_function option was deleted in this commit: 63d8428

But how does this line work then? https://github.com/williamFalcon/pytorch-lightning/blob/master/pytorch_lightning/callbacks/pt_callbacks.py#L223-L224

Also, there were some save_function=None in docs, which make it somehow confusing.
