Description

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.
