Jersey 2 with guice bind is not able to bind resources

As part of migrating Jersey from 1.19.4 to 2.39.1, we are facing some issues with guice bind.

Here is the draft PR: https://github.com/apache/hadoop/pull/5768

All updated dependencies are defined here: https://github.com/apache/hadoop/pull/5768/files#diff-df2aa66a3757d73c93849b3a279d42a4634b0aed3550cdd2ead32d2fa06bf49e (hadoop-project/pom.xml)

We have a test TestWebApp https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/test/java/org/apache/hadoop/yarn/webapp/TestWebApp.java#L245

```
@Test
void testCustomRoutes() throws Exception {
WebApp app =
WebApps.$for("test", TestWebApp.class, this, "ws").start(new WebApp() {
@Override
public void setup() {
bind(MyTestJAXBContextResolver.class);
bind(MyTestWebService.class);

route("/:foo", FooController.class);
route("/bar/foo", FooController.class, "bar");
route("/foo/:foo", DefaultController.class);
route("/foo/bar/:foo", DefaultController.class, "index");
}
});
String baseUrl = baseUrl(app);
try {
assertEquals("foo", getContent(baseUrl).trim());
assertEquals("foo", getContent(baseUrl + "test").trim());
assertEquals("foo1", getContent(baseUrl + "test/1").trim());
assertEquals("bar", getContent(baseUrl + "test/bar/foo").trim());
assertEquals("default", getContent(baseUrl + "test/foo/bar").trim());
assertEquals("default1", getContent(baseUrl + "test/foo/1").trim());
assertEquals("default2", getContent(baseUrl + "test/foo/bar/2").trim());
assertEquals(404, getResponseCode(baseUrl + "test/goo"));
assertEquals(200, getResponseCode(baseUrl + "ws/v1/test"));
assertTrue(getContent(baseUrl + "ws/v1/test").contains("myInfo"));
} finally {
app.stop();
}
}

```

The idea here is to ensure that custom routes are served with the above mentioned endpoints.

Moreover, MyTestJAXBContextResolver and MyTestWebService are used to bind requests starting with "ws/v1/test".

The changes done for MyTestJAXBContextResolver: https://github.com/apache/hadoop/pull/5768/files#diff-52936fdf3657b9acf3cffa439cf5c0b71737d51d8d473329843e66ca462aa306

and MyTestWebService (without changes): https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/test/java/org/apache/hadoop/yarn/webapp/MyTestWebService.java

Since guice bind is not able to bind the classes, `getResponseCode(baseUrl + "ws/v1/test")` always results into 404.

i have also tried adding the classes/packages with ResourceConfig but it is only able to instantiate MyTestJAXBContextResolver, it is still not able to redirect `ws/v1/test` GET to MyTestWebService.

guice-hk2 is in the classpath.
the test belongs to hadoop-yarn-common module.

Edit:
additional reference: we create embedded Jetty server to server http requests in [HttpServer2](https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/http/HttpServer2.java)
