    Follow the hosting chain to find the host server

    Since a hosting chain may exist among several node templates (e.g.
    a web application hosted on an application server, the application
    server hosted on a web server, the web server hosted on a compute
    node) update the code to follow the chain and return the actual
    compute node host. The unit test for this patch will be covered by
    bug #1435545.
