> If anything goes wrong in the stack-advisor scripts, it should be propagated to the API response so that the user can take appropriate action. 
> For example in script's main() I threw an exception
> {code}
> raise StackAdvisorException("I will fail!")
> {code}
> However the API response was 
> {code}
> 400 - Bad Request
> Error occured during stack advisor command invocation
> {code}
> Any _StackAdvisorException_ means a semantic issues, and should be reported as {{400-Bad Request <message>}}. 
> Any other exceptions should be returned as {{500-Internal Server Error <message>}}.
> Any other types of failures should also be accounted for (compilation issues, NPEs, etc.)
