Add support for managed JAX-RS subresource locators

[BrianSetz]

This addresses #2168. The problem originates from the fact that context.getResourceTypeResolver().resolve(method.returnType()); was assumed to contain the type of the sub resource. However, when dealing with managed resources, the methodReturnType will be set to Class<SomeManagedResource> which will not be found by context.getIndex().getClassByName(methodReturnType.name()); (since it expects SomeManagedResource and not Class<SomeManagedResource> and therefore the managed sub resource is not processed.

Questions:

• I am not familiar with the Jandex API at all, so please advice if there is a better way to implement the extraction of the type parameter from the generic class.
• Where is the best place to introduce tests for this? I quickly tested this by modifying the GreetingGetResource.

Thanks for the PR @BrianSetz. This is going in the right direction. For testing, you can maybe modify the test below by changing the return type of one or two sub-resource locators to use a Class type. You won't need to change and expectations and the scenario will cover your change.
