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