> Currently the UI loads *all* the host-components for a service just to calculate the
status of a service. So if YARN, HDFS are installed on a 1000 node cluster, we get 2000 host-components
in response just to calculate the color of 2 services (stopped=red, started=green, starting=blinking-green,
stopping=blinking-red, etc., unknown=yellow)
> This is not scalable on the browser. We want the API to roll-up the host-component statuses,
and correctly update the {{ServiceInfo/state}} of the service. This will help UI in not loading
all host_components.
