     * This is the "Create VF Module" web service implementation. It will instantiate a new VF Module of the requested
     * type in the specified cloud and tenant. The tenant must exist before this service is called.
     *
     * If a VF Module with the same name already exists, this can be considered a success or failure, depending on the
     * value of the 'failIfExists' parameter.
     *
     * All VF Modules are defined in the MSO catalog. The caller must request one of the pre-defined module types or an
     * error will be returned. Within the catalog, each VF Module references (among other things) a cloud template which
     * is used to deploy the required artifacts (VMs, networks, etc.) to the cloud. In this adapter implementation, that
     * artifact is expected to be a Cloudify blueprint.
     *
     * Depending on the blueprint, 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 module or an error will be thrown.
     *
     * The method returns the vfModuleId, a Map of 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 Module. This is useful if a
     * VF module is successfully created but the orchestration fails on a subsequent step.
     *
     * @param cloudSiteId CLLI code of the cloud site in which to create the VNF
     * @param cloudOwner cloud owner of the cloud site in which to create the VNF
     * @param tenantId Openstack tenant identifier
     * @param vfModuleType VF Module type key, should match a VNF definition in catalog DB. Deprecated - should use
     *        modelCustomizationUuid
     * @param vnfVersion VNF version key, should match a VNF definition in catalog DB Deprecated - VF Module versions
     *        also captured by modelCustomizationUuid
     * @param genericVnfId Generic VNF ID
     * @param vfModuleName Name to be assigned to the new VF Module
     * @param vfModuleId Id of the new VF Module
     * @param requestType Indicates if this is a Volume Group or Module request
     * @param volumeGroupId Identifier (i.e. deployment ID) for a Volume Group to attach to a VF Module
     * @param baseVfModuleId Identifier (i.e. deployment ID) of the Base Module if this is an Add-on module
     * @param modelCustomizationUuid Unique ID for the VF Module's model. Replaces the use of vfModuleType.
     * @param inputs Map of key=value inputs for VNF stack creation
     * @param failIfExists Flag whether already existing VNF should be considered
     * @param backout Flag whether to suppress automatic backout (for testing)
     * @param msoRequest Request tracking information for logs
