[Tracking] Deprecations related to 5.0

[abidlabs]

Things to deprecate / remove in 5.0:

• concurrency_count in queue()
• additional_inputs_accordion_name in ChatInterface
• every in events
• thumbnail in Interface
• root in gr.FileExplorer
• signed_in_value in gr.LoginButton
• gr.LogoutButton

[abidlabs]

Many of our constructors have gotten rather large so we should make more args keyword-only args, e.g. in Interface and Examples

• Integrate ?
• HFDatasetSaver 🙈

[abidlabs]

Yes let's remove HFDatasetSaver, we can potentially add a better abstraction in 5.0 (we've heard various proposals from the argilla team) or at least provide a tutorial on how to do this yourself.

For integrate(), I'm inclined towards leaving it in. It hasn't caused any issues for us recently and there might be users who are using gradio in nice ways with wandb/comet

[abidlabs]

Going to close this for now as all of these are addressed. I anticipate that we might deprecate more things, but we can create new issues for those
