Separate existing service project into weba_app and service

• Separate ci-service into ci-webapp (war) and ci-service (jar)
• Remove the dependency of file-service from ci-webapp, since we decide that each webapp (file-webapp, ci-webapp, paw-webapp) has only dependency to its service (file-service, ci-service, paw-service)
• Creating new ci-all-webapp project to include file-service, ci-service, and paw-service
