---------------------------------------

    Description: 
For request URL:
/api/v1/clusters/cl/hosts?fields=host_components/HostRoles/service_name
Response missing "service_name" field:

{
  "href" : 
"http://192.168.56.101:8080/api/v1/clusters/cl/hosts?fields=host_components/HostRoles/service_name";,
  "items" : [
    {
      "href" : 
"http://192.168.56.101:8080/api/v1/clusters/cl/hosts/dev01.hortonworks.com";,
      "Hosts" : {
        "cluster_name" : "cl",
        "host_name" : "dev01.hortonworks.com"
      },
      "host_components" : [
        {
          "href" : 
"http://192.168.56.101:8080/api/v1/clusters/cl/hosts/dev01.hortonworks.com/host_components/APP_TIMELINE_SERVER";,
          "HostRoles" : {
            "cluster_name" : "cl",
            "component_name" : "APP_TIMELINE_SERVER",
            "host_name" : "dev01.hortonworks.com"
          }
        }
     ]
}
{noformat}
Also filtering by service_name doesn't work:
Request: 
/api/v1/clusters/cl/hosts?host_components/HostRoles/service_name=HDFS&fields=host_components/HostRoles/service_name
Return empty items
