Why aren't RestClient::RequestTimeout exceptions caught and re-raised as CloudinaryExceptions?

The `call_api` method only raises `CloudinaryExceptions` under certain circumstances, like JSON parse errors or certain failure codes. But if the underlying RestClient times out, it's not caught so it bubbles out to the calling code.

https://github.com/cloudinary/cloudinary_gem/blob/master/lib/cloudinary/uploader.rb#L293-L308

Is this an oversight or intentional?

It's nice to only think about the Cloudinary API when coding and not have to worry about libraries that Cloudinary uses (like RestClient).

I'd be happy to submit a PR on this, but I wanted to start with a question to see if I'm not understanding the rationale here. Thanks!
