NeutronExceptions have a 'message' class attribute that holds the generic error message template, e.g. "Network %(network)s not found", unfortunately, because the names are the same, it was overshadowing the actual exception instance 'message', e.g. "Network 1 not found", after translation when the exception was serialized to JSON. This patch puts the exception's actual message in a new field called 'msg' and overwrites NeutronException unicode() so that 'msg' is used during serialization and we'll get the correct message on the REST API response. Fixes bug: #1212882 Change-Id: I3965bffb1c2c2eee0af440d1ecd30ccb3bb958d5
