Allow deployments to get access to the META-INF folder of their dependency module

Currently there is absolutely no mechanism (outside of manipulating dependencies programmatically through a subsystem) for deployments to get access to some META-INF/xyz files from a module that they declare as a dependency, except are in META-INF/services.

This is a serious impediment when considering the installation of third party libraries as shared libraries (modules) in JBoss AS. Some frameworks may rely upon locating internal descriptors in META-INF, and if the libraries are installed as modules, the descriptors are not accessible to the framework. Essentially, there is no way of accessing resources under META-INF unless they are either services, or the library is packaged in the deployment.
