 * Yang model for the Application Controller (APP-C) component of ECOMP

 * directed graph is set by properties and cannot be changed dynamically.
 *
 * The services exposed by this provider are:
 *
 * restart-vnf:
 *    Used to request a restart of a virtual network function (a VM).
 *
 * rebuild-vnf:
 *    Used to request a rebuild of a virtual network function (a VM).
