Main Success Scenario

1. An authenticated user browses to the OpenNMS WebUI.
2. User selects an OpenNMS entity (node, interface, service).
3. User clicks on the "Poll Now" link in the entity menu bar.
4. The webUI takes the user to a demand poll results page. The results will show the per-service status, in particular whether the poll is scheduled, whether it is currently running, or completed. If the poll is completed, the up/down status will be shown, as well as the message from the poll result.
5. There will be some way to refresh the poll status page, manually and/or automatically.
