The instance actions API in nova is very similar. Rather than build a 
new "user messages" API in nova I'm just talking about providing more 
detail on the actual error that occurred per failed event per action, 
basically the same as the user would see in a fault message on the 
server when it's in ERROR status. Because right now the instance action 
and events either say "Success" or "Error" for the message/result which 
is not useful in the Error case.
