FM System Heal 

Hi,
At the fm-system documentation, talking about heal lifecyle event but i didn't find any example.  https://github.com/openbaton/fm-system#how-the-heal-method-works

I tried to define in lifecycle_events but NFVO not accepting 
{"event": "HEAL",
 "lifecycle_events": ["heal.sh"] }

How to runs a specified heal script and define heal event in vnfd?
