  - Merge "Adding query APIs for AppIntents"
  - Adding query APIs for AppIntents

    In this patch the following tasks where performed:
    1. Added APIs for query Intents for each App
    in the compositeApp. For example, you can see all
    intents of collectd or prometheus seperately if
    both formed a compositeApp Collection.

    2. Added 'provider-name' parameter to denote the cluster
    objects used in all intents. Earlier we had only
    clusterName and clusterlabel to denote a cluster.
    Modified the tests also for this.

    3. Fixed bugs in the plugin_collection_v2.sh.

    4. Fixed some minor logging and formatting bugs.
