Module Refactoring to separate interface and impl

Created two modules:
- cxfatwork-osgi-resources to hold the xsd schemas and the autogenerate
classes for the exposed resources
- cxfatwork-osgi-jaxrs-impl to hold the specific jars implementation,
separated by the interface
Updated the previous module extracting implementation classes and the
resources in order to have only the wadl and the auto generated
interface
Updated the cxfatwork-rs to include the new modules
