27 Main program that implements a reference NFVO (Network Functions Virtualisation Orchestrator).
28 It interfaces with an NFV VIM through its API and offers a northbound interface, based on REST (openmano API),
29 where NFV services are offered including the creation and deletion of VNF templates, VNF instances,
30 network service templates and network service instances.
32 It loads the configuration file and launches the http_server thread that will listen requests using openmano API.
