> Ambari UI when loading services, loads *all* host-components to get service specific
metrics, which is available only on master host-components. Loading of client/worker host-components
is not needed on dashboard and services pages. 
> Hence in API we need a {{type}} field on host_components. This should indicate whether
the host_component is master/worker/client/other type. Also, this field should be query-able.

> So the below query should give me services with their master host-components, and their
jvm heap metrics.
