As of 7.13, Che server is built from 2 containers and one maven assembly:

• che dashboard (docker)
• che workspace-loader (docker)
• che parent (maven)
• che server (maven)

So, the crw_master build needs to be updated to use this new approach, and the crw 2.2 server assembly needs to be updated similar to the way the che server was for 7.13.
