Review request for Ambari, Andrii Tkach, Jaimin Jetly, and Yusaku Sako.

Bugs: AMBARI-12656

Repository: ambari


When the page of hosts has already been loaded to FE model store, we should avoid trigger
hosts loading when user switch in/out hosts tab. Just reuse the front-end model to render
the page and schedule an update request after a few seconds.
