Example "Microprofile Hello World Explicit" is broken

[tomas-langer]

The port we get from ServerCdiExtension is always 0.
This seems to be caused by obtaining a different instance of ServerCdiExtension from BeanManager than the one that starts the server.

To start the example, the following configuration must be added to application.yaml:

mp:
  initializer:
    allow: true
    warn: false
