Description

See attached.
1. We can proactively detect that ATS is not running, and show an appropriate error message saying "Jobs data cannot be shown since YARN App Timeline Server is not running."
2. We need a generic error handling in case of 400 from server, saying "Unable to load data." instead of showing "Loading..." forever.
