Don't document the ServerResourceProducer as there should be no real need for users to implement it. The same thing can be achieved with JUnit API's.

-== Extending Resource Injection
-
-The framework supports custom resource injection via the `ServerResourceProducer` SPI.

-=== Implementing a Resource Producer
-
-Create a class that implements `org.wildfly.testing.junit.extension.api.ServerResourceProducer`:

-=== Using the Custom Producer
-
-Now you can inject the custom resource type:

-@WildFlyTest
-public class RestApiTest {

-    private Client client;

-                .request()
-                .get();
