Deprecation of pushing arguments for cleaner DX in Keras mixin

[merveenoyan]

Currently push_to_hub_keras looks like this:

def push_to_hub_keras(
    model,
    repo_path_or_name: Optional[str] = None,
    repo_url: Optional[str] = None,
    commit_message: Optional[str] = "Add model",
    organization: Optional[str] = None,
    private: Optional[bool] = None,
    api_endpoint: Optional[str] = None,
    use_auth_token: Optional[Union[bool, str]] = True,
    git_user: Optional[str] = None,
    git_email: Optional[str] = None,
    config: Optional[dict] = None,
    include_optimizer: Optional[bool] = False,
    **model_save_kwargs,
):

But it's not intuitive and clean. Would be better if we'd do

def push_to_hub_keras(
    model,
    repo_id: str,
    commit_message: Optional[str] = "Add model",
    private: Optional[bool] = None,
    use_auth_token: Optional[Union[bool, str]] = True,
    config: Optional[dict] = None,
    include_optimizer: Optional[bool] = False,
    **model_save_kwargs,
):

As put by @osanseviero here.
We need to deprecate a couple of arguments and put FutureWarnings if provided and then remove completely.

Nice proposal, I agree that what you propose here is much cleaner! It is similar to what is proposed in #847, with some additional arguments stripped away. I'd be very eager to hearing your feedback and proposals on that PR!

Since #847 is merged, previous signature is deprecated and will change in v0.12 to something very similar to what is proposed here (see comment here).

Therefore I'm closing this issue :)
