Nova is not able to reliably distinguish between port OverQuota 409 errors and IpAddressInUse 409 errors when setting up networks for instances. The client needs to provide a more granular exception so nova can translate the error to it's own set of exceptions. Also adds a test case for the exception_handler_v20 utility method which was lacking explicit test coverage before this change.
