@Bean
    public ClientFactory clientFactory() {
        return ClientFactory.insecure();
    }
Returns a custom {@link ClientFactory} with TLS certificate validation disabled,
which means any certificate received from the server will be accepted without any verification.
It is used for an example which makes the client send an HTTPS request to the server running
on localhost with a self-signed certificate. Do NOT use the {@link ClientFactory#insecure()} or
{@link ClientFactoryBuilder#tlsNoVerify()} in production.
