Break ci-management jobs group down

Break ci-management jobs group down

While trying to implement / revert some of the work for the Jenkins
managed configuration jobs we've run into some strange problems.
Unfortunately there is currently a bug that we're hitting in global-jjb
that is causing all configurations to disapear.

This change switches from using the job group to defining just the jobs
we want in the system right now so that we don't keep running into this
bug / problem. It also allows us to continue testing configuration
changes without fear of breaking the system.
