Shi Lu updated HELIX-25:
------------------------

    Assignee: dafu  (was: Shi Lu)
     Summary: setConfig should check if instance exist or not when setting PARTICIPANT config  (was: enableInstance should check if instance exist or not)

We need to make sure that setConfig does nothing when setting a participant config which is not added into cluster yet. As some code in helix use the childnames of /CONFIGS/PARTICIPANT  to get the list of instances in the cluster
