Friendly magic - eliminate the need to @BeforeEach a context.setTarget(new HttpTestTarget("localhost", 8081))

We can elimiminate some boilerplate, as we do for other extensions like rest-assured.

At the moment, every provider tests need boilerplate like the following:

    @ConfigProperty(name = "quarkus.http.test-port")
    int quarkusPort;


    @BeforeEach
    void beforeEach(PactVerificationContext context) {
        context.setTarget(new HttpTestTarget("localhost", this.quarkusPort));
        [...]

In a @QuarkusTest, there's only one set of values for the host and port, so we should do that context initialisation automatically.

The QuarkusTestExtension.getEndpointPath() method may help with this. It's also worth looking at how it's done for RestAssured - instead of instrumentation, the test extension calls a static helper provided by rest assured itself:

                    runningQuarkusApplication.getClassLoader().loadClass(RestAssuredURLManager.class.getName())
                            .getDeclaredMethod("setURL", boolean.class, String.class).invoke(null, secure, endpointPath);
