Expose JAX-RS resources as children of the subsystem

Servlets, EJBs, WebSockets, JPA, etc expose its components as children of the subsystem in the management API. For example to list the stateless EJBs of a deployment:

[standalone@localhost:9990 /] /deployment=cdivsejb.war/subsystem=ejb3:read-children-resources(child-type=stateless-session-bean)

This makes it specially easy to navigate trough the web console (attached screenshot).

To read JAX-RS resources, the command would be:
[standalone@localhost:9990 /] /deployment=cdivsejb.war/subsystem=jaxrs:show-resources()

I propose to make deprecate the show-resources operation and create a new "resources" child, containing the Rest resources.
