Now we package the deployment with WildFly runtime in an image. This has this limitation: 

1. When there is deployment change, we have to rebuild the whole image.
2. If User only wants to upgrade the WildFly version to pickup some CVE and other patches, it has to rebuild the images. 

To resolve this limitation, we create a module to build the wildfly runtime image without package the deployment. This includes the WFLY server and other required configuration by running the jboss CLI.
