Review comment:
The existing [getComponentErrorInfo()](https://github.com/Crim/storm/blob/sp/STORM-3652/storm-webapp/src/main/java/org/apache/storm/daemon/ui/UIHelpers.java#L1430-L1443) method adds the remaining properties that the UI is expecting to properly render the error. See [topology-page-template.html](https://github.com/Crim/storm/blob/sp/STORM-3652/storm-webapp/src/main/java/org/apache/storm/daemon/ui/WEB-INF/templates/topology-page-template.html#L565-L574)
