Allow EE deployments as OSGi bundles

This essentially means that you can put OSGi metadata into an EE deployment manifest, which essentially makes it an OSGi bundle.

Deployment unit processing should be such that the EE bundle gets resolved according to it's defined capabilities/requirements. Subsystem processors should not need to care whether the Module was created as a result of OSGi resolution or by the ModuleSpecProcessor.

This task is complete when we can do this with the EE core technologies (i.e. webapp, ejb3, cdi)
