> We've seen that the Hosts page loads very slowly when metrics API calls are
> responding slowly. Under this condition, shutting down AMS makes the Hosts
> page responsive again.
> We should make Hosts page responsiveness independent of metrics API call
> latency by loading non-metric data and rendering the page first, and then
> lazy loading metrics info.
