MP Testing

Resolves #2364

Support for MP testing allowing the following:

@HelidonTest
class TestAutoDiscovery {
    @Inject
    @ConfigProperty(name="app.greeting")
    private String greeting;

    @Test
    void testGreeting() {
        assertThat(greeting, is("TestHello"));
    }
}

Or for more complex tests:

@HelidonTest
@DisableDiscovery
@AddBean(MyBean.class)
@AddExtension(ConfigCdiExtension.class)
@AddConfig(key = "app.greeting", value = "TestHello")
class TestNoDiscovery {
    @Inject
    private MyBean myBean;

    @Test
    void testGreeting() {
        assertThat(myBean, notNullValue());
        assertThat(myBean.greeting(), is("TestHello"));
    }
}
