I'm very worried about introducing a feature which can allow unhealthy 
instances live forever. Furthermore this information isn't exposed on the 
Aurora UI or Observer UI so there isn't an easy way to check if an instance has 
health checking disabled or not. A user can be completely oblivious that health 
checking of their instance has been disabled.
