Issue 50246 - Fix the regression in old control tools
Bug Description: The old control tools - status-dirsrv, start-dirsrv,
stop-dirsrv, restart-dirsrv stopped working properly after
the /etc/sysconfig/dirsrv removal.
Fix Description: Make them the direct systemctl command wrappers and
don't look for instances in /etc/sysconfig/dirsrv.
Fix UI. Make it use the new dsctl tools. Extend dsctl status (add JSON).
Also, remove the dragon warning because it breaks the QE test reports
when we run all the tests (we don't use DEBUGGING mode there
because it doesn't remove the instances).
The deprication warning should be enough for now.
