ManagedBean annotation
* - CDI Bean - If the servlet is deployed in a bean archive
* - EE Component - If this is an EE deployment and the servlet is not one of the above
* - Normal Servlet - If the EE subsystem is disabled
*
*
* For ManagedBean Servlets no action is necessary at this stage, as the servlet is already registered as a component. For CDI
* and EE components a component definition is added to the deployment.
*
* For now we are just using managed bean components as servlets. We may need a custom component type in future.
