Mention the need to expose the client in the Spring config

[samudurand]

My trace id was not being transmitted forward to the other service that I was calling with OpenFeign. The solution was to expose the client, as mentioned in this post https://stackoverflow.com/a/58696749/1660475

    @Bean
    public Client feignClient() {
        return new Client.Default(null, null);
    }

This should really be part of the readme.
