commit 8f3213cfceb548bec37b2e0668c670fe552934b5

    Fix: stonith-ng: Trigger on constraints added to cib
    
    The simple search for 'rsc_location' just triggered on delete.
    'constraints' is found both in additions and deletes.
    A smarter check might reduce the number of unneeded triggers but
    probably isn't worth the effort.
    Add some trace-logging to facilitate tracking down similar issues.
