Add setup stage to only load project configuration

RUN_TYPE choice parameter added with 'normal' and 'setup' runs.
Only 'Setup' stage is executed when 'setup' is chosen.
'Setup' stage only loads confifuration and marks result as NOT_BUILT.
'Setup' stage is also run when 'queue' method (from Job DSL plugin)
is called with JCasC.
