SUBSCRIBING - Subscribing to information. (1) new ARTIFACT TYPE can subscribe to that new type, DCAE makes new service, knows to download the new type, (2) all is packaged in the CSAR package. 
ARTIFACT TYPE: Application that receives the artifact needs to know what it is. Will DCAE try one way to read, or another. QUESTION do we need a new Artifact Type or can we reuse the DCAE_TOSCA, DCAE_JSON.
