Related Epic: SDNC-887

There are two new services arround SDN-R Mountpoints planned:

• Use DMaaP as ONAP internal communication services
• Create two seperate bundles in ccsdk/feature-sdnr/wt
• Overall architecture: SDNC-888

Mountpoint provider

1. Deliver SDN-R Mountpoint status changes over DMaaP
2. Stories are: SDNC-889 
3. Proposed bundle name: sdnr-wt-mountpoint-state-provider
4. Register listener to MDSAL for mountpoint changes and provide related information
5. Related disussion: model-driven DMaaP Agent
6. Uses ClusteredDataTreeChangeListener for NetconfChangeListener

Mountpoint registrar for VES

1. Manage SDN-R Mountpoints
2. Methods are: Create, Remove
3. Stories are: SDNC-890
4. Proposed bundle name: sdnr-wt-mountpoint-registrar
5. VES message: pnfRegistration

Integration test

1. Story: SDNC-891

Configuration files

1. The mountpoint-registrar bundle uses 1 configuration file (it is located in the $ODL_HOME/etc directory by default) - 
   1. dmaap-vesmsg-listener.properties - This file contains a property key by the name - subscriptions and its values are fully qualified Java class names and consumer properties file names separated by : (colon) and ; (semicolon) Ex: subscriptions=org.onap.ccsdk.features.sdnr.wt.mountpointregistrar.impl.DMaaPPNFRegVESMsgConsumer:pnfRegVESmsgConsumer.properties
      In the example above, the subscriptions property value contains 2 parts separated by a : (colon). The value before the : (colon) contains a fully qualified Java class name which implements the DMaaPVESMsgConsumer class. The value after the : (colon) contains a consumer properties file as understood by DMaaP consumer implementation. There can be any number of "Java class : consumer properties file" values separated by a ; (semicolon) for the subscriptions property. Note: the example value shown above is identical to the value in the dmaap-vesmsg-listener.properties file shipped with the bundle and this should not be changed. 
2. The consumer properties file contains information about the Kafka topic, consumer ID, group ID, authorization information etc. This bundle ships a consumer properties file with the name pnfRegVESmsgConsumer.properties and this file is by default in the $ODL_HOME/etc directory.

Usage

pnfRegistration VES Message flow 

Message flow (for registering a mountpoint with TLS protocol)
