Create a Protocol processor SPI for modifying the final deployment generated by the DeploymentPackager

In some cases we need to modify the Protocol generated Deployment.

In the case of CDI, it's BeanManagers are hierarchical, a BeanManager created for a ejb-jar in a ear is not visible to a war unless the war also contains a beans.xml. When using the Servlet Protocol, a war is added without a beans.xml since the protocol it self is unaware of CDI, and Beans are never injected into the testcase.

DeploymentProcessor.process(TestClass relevant class, TestDeployment auxAndApplicationArchives, Archive<?> finalDeployment);
