ONAP Heat Post Orchestration & VNF Configuration
------------------------------------------------

Heat templates should contain a minimum amount of post-orchestration
configuration data. For instance, *do not* embed complex user-data
scripts in the template with large numbers of configuration parameters
to the Heat template.

-  VNFs may provide configuration APIs for use after VNF creation. Such
   APIs will be invoked via application and/or SDN controllers.

*Note:* It is important to follow this convention to the extent possible
even in the short-term as of the long-term direction.
