Description

The UI was halting page loads with:

Case Comment: Uncaught TypeError: Cannot read property 'HostRoles' of undefined(anonymous function) @ app.js:56797
App.serviceMetricsMapper.App.QuickDataMapper.create.yarnMapper @ app.js:56772
App.serviceMetricsMapper.App.QuickDataMapper.create.mapExtendedModel @ app.js:56559(anonymous function) @ app.js:56520
App.serviceMetricsMapper.App.QuickDataMapper.create.map @ app.js:56512newFunc @ vendor.js:2627(anonymous function) @ app.js:161511

The UI should tolerate or somehow warn when ATS is not installed.
