options: A Namespace that has fields for each parameter that can be

AppControllerException: If the AppController on the head node crashes.
When this occurs, the message in the exception contains the reason why
the AppController crashed.
BadConfigurationException: If the user passes in options that are not
sufficient to start an AppScale deployment (e.g., running on EC2 but
not specifying the AMI to use), or if the user provides us
