Use API directly from API catalog/documentation/API view

[bajiat]

Make sure the Apinf documentation viewer uses Apinf to make the API calls so that the calls go through the proxy.

Creating an option for using API from API catalog or API page or from documentation. This could for example be a button.
This would simplify the workflow for testing/sandboxing: instead of consumers finding a place where to copy their key and creating the API call in URL field with the key.

Definition of done

• Verify if the documentation viewer has an option for using/testing the API to make request.
