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),
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.
