Currently error handling in Tuskar-UI involves a lot of repeated code, as the same pattern is used everywhere and the same API calls tend to be handled in the same way no matter where they appear. This patch introduces a decorator that can be used to add default error handling to all API calls that take a request as a parameter. That default error handling can be disabled or modified using the special parameters passed to the call, all of which start with "_error" to avoid conflicts.
