Add a delay indicator to entity tables, service table, dashboard, and reports pages in new UI
Reporting this on Warren's behalf. Seen in a FreeNAS system updated to FreeNAS-11.2-MASTER-201807260859.
We are noticing that some screens (Dashboard, Reporting, Plugins/Available, and Services were observed) can take a few moments or longer to load, especially when the web browser cache is clear or loading the page for the first time. It would be useful to the user to see some kind of loading widget or activity on the screen to indicate the UI is loading or "doing something" while the menu item isn't displaying anything.
