Make it easier to change AuthorizeEndpoint and Client

To make it easier to change the AuthorizeEndpoint and Client we set them as class variables. Then people inheriting from the view are able to easily change them. In my personal case this helps with skipping consent more explicitly as defined in issue https://github.com/juanifioren/django-oidc-provider/issues/278
