Allow process_response and process_slo to raise exceptions

Why raise exceptions instead get them on the errors var and raise after the process method ends if you want?

Thank you, I didn't realize that the error message was stored into the error reason. That said it is nice to be able to see the actual exception so you know exactly what line it was raised on in the validation code. This is helpful in determining exactly what rule was broken and if it is possible to disable that check.

Currently the raise_exceptions is a useful feature that isn't really accessible to the caller unless they make their own response object.
