Review Comment:
   Please consider not integrate the Throwable in message. If we do it this 
way, it only print out a short description of this throwable.
   We may want to print the stack trace and other information.  Please consider 
something like. 
   ``` 
    public void logError(Message message, Class classInfo, Exception e, String 
additionalInfo,
         HelixManager manager) 
   ```
