Chaynika Saikia bc52ae4219 Add insufficient space async error in create vol ... cinder does not provide an async error message when a new volume is created from an image if there is insufficient space to download the image. The changes are made such that if there is an IOError in fetch() or insufficient space error from check_available_space() cinder message API generates an async error message for the user. A new exception ImageTooBig() has been created to handle this error and whenever this exception is come across, cinder generates an error message. Changes are made in the create_volume flow to handle this exception and generate the message. Changes are made in image_utils.py so that whenever there is not enough space, the appropriate exception is raised. New action and detail are added to message_field.py for this type of error.
