     * If a network with the same name already exists, this can be considered a
     * success or failure, depending on the value of the 'failIfExists' parameter.
     *
     * There will be a pre-defined set of network types defined in the MSO Catalog.
     * All such networks will have a similar configuration, based on the allowable
     * Openstack networking definitions. This includes basic networks, provider
     * networks (with a single VLAN), and multi-provider networks (one or more VLANs)
     *
     * Initially, all provider networks must be "vlan" type, and multiple segments in
     * a multi-provider network must be multiple VLANs on the same physical network.
     *
     * This service supports two modes of Network creation/update:
     * - via Heat Templates
     * - via Neutron API
     * The network orchestration mode for each network type is declared in its
     * catalog definition. All Heat-based templates must support some subset of
     * the same input parameters: network_name, physical_network, vlan(s).
     *
     * The method returns the network ID and a NetworkRollback object. This latter
     * object can be passed as-is to the rollbackNetwork operation to undo everything
     * that was created. This is useful if a network is successfully created but
     * the orchestration fails on a subsequent operation.
