This adjusts the AuthRequest Authz implementation behave similarly to the other implementations in as much as Authelia can return the relevant redirection to the proxy and the proxy just utilizes it if possible. In addition it swaps the HAProxy examples over to the ForwardAuth implementation as that's now supported.

Since nginx doesn't do portal URL detection we have to skip returning an error on the legacy authz implementation when the portal URL isn't detected. This issue only exists in unreleased versions.
