separate providers and models settings area

[manos-msdn]

Currently we have only "Providers" section, which in reality groups providers and models, plus a few other settings.

So if we need to change the provider key we need to then manually go and change the key in every model we have from this provider, which is tedious and error prone process, plus we can't even see the key to check if we've changed it already or not.

Would be quite handy if we could have a "Provider Settings" area in the settings where we set the API key for this provider (and any other "provider-level" settings , then re-use this provider object in every "Model" object we want to have for this provider. Instead of having to enter the key and any other provider level settings separately for each "Provider" in the current config (where really, it's a provider + model together with the provider stuff repeated)

I think it will be a bit cleaner organisation of the settings and better UX

Thanks

Edit: on a second thought, perhaps we don't need this, because we might want to have different keys even with the same provider... anyway leaving the discussion open for opinions, the owners/admins of the project can close it if needed, thanks again
