     * This is the asynchronous "Create VNF" web service implementation.
     * It will create a new VNF of the requested type in the specified cloud
     * and tenant. The tenant must exist before this service is called.
     *
     * If a VNF with the same name already exists, this can be considered a
     * success or failure, depending on the value of the 'failIfExists' parameter.
     *
     * All VNF types will be defined in the MSO catalog. The caller must request
     * one of these pre-defined types or an error will be returned. Within the
     * catalog, each VNF type references (among other things) a Heat template
     * which is used to deploy the required VNF artifacts (VMs, networks, etc.)
     * to the cloud.
     *
     * Depending on the Heat template, a variable set of input parameters will
     * be defined, some of which are required. The caller is responsible to
     * pass the necessary input data for the VNF or an error will be thrown.
     *
     * The method sends an asynchronous response to the notification URL when
     * processing completes. The createAsyncResponse contains the vnfId (the
     * canonical name of the stack), a Map of VNF output attributes, and a
     * VnfRollback object. This last object can be passed as-is to the
     * rollbackVnf operation to undo everything that was created for the VNF.
     * This is useful if a VNF is successfully created but the orchestrator
     * fails on a subsequent operation.
     *
     * Note: this method is implemented by calling the synchronous web method
     * and translating the response to an asynchronous notification.
     *
     * @param cloudSiteId CLLI code of the cloud site in which to create the VNF
     * @param tenantId Openstack tenant identifier
     * @param vnfType VNF type key, should match a VNF definition in catalog DB
     * @param vnfName Name to be assigned to the new VNF
     * @param inputs Map of key=value inputs for VNF stack creation
     * @param failIfExists Flag whether already existing VNF should be considered
     *        a success or failure
     * @param msoRequest Request tracking information for logs
     * @param notificationURL the target URL for asynchronous response
