Storm UI - Topology action button error response hardcoded

Right now on confirming the topology ui action buttons (https://github.com/apache/storm/blob/4966d7a69318d2ca690c47dd43466b03574e5e9e/storm-core/src/ui/public/templates/topology-page-template.html#L607) the UI behaviour is to reload the page always (https://github.com/apache/storm/blob/10d381b303c9176ede0d1260428ad61c7757e396/storm-core/src/ui/public/js/script.js#L169) and in case of an error display a hardcoded error message "Error while communicating with Nimbus."

While this behaviour is okay for workflows with no authorization it gets confusing when the action buttons are put behind some form of authorization. It will be much clearer to define an error message format and have the UI display the correct error message on authorization and other non-nimbus related failures.
