Spring Cloud Netflix Create integration test for eureka with jersey

Now that #3785 is done, we should have an integration test that makes certain, jersey still works. Likely needs to be in a separate integration tests module

Not sure what would be new to test. Jersey deps are made optional in the module, that keeps the autowired DiscoveryClientOptionalArgs bean on existing JerseyOptionalArgsConfigurationTest.java test class to remain not null and verify still that Jersey discovery client is there.
