[IMP] auth_jwt: add public_or_jwt auth method

This method is useful for public endpoints that need
to work for anonymous user, but can be enhanced when
an authenticated user is know.

A typical use case is a "add to cart" enpoint that can
work for anonymous users, but can be enhanced by
binding the cart to a known customer when the authenticated
user is known.
