Implement CDI-392

So far the conclusion has been:

• Allow the following methods in ABD:
  getBeans(String)
  getBeans(Type, Annotation...)
  getPassivationCapableBean()
  resolve()
  validate()
  resolveObserverMethods()
  resolveDecorators()
  resolveInterceptors()

Furthermore, ABD addBean(), and addObserverMethod() methods will be queued and applied when all ABD invocations finish. (Basic validation e.g. ExternalBeanAttributesFactory.validateBeanAttributes() should be performed immediatelly)

• The following methods are allowed in ADV:
  getReference()
  getInjectableReference()
