Now, DSS only supports to import/export Linkis BML resources or one inputStream,
so the resourceMap is consisted of `resourceId` and `version` if you choose Linkis BML resources,
or `InputStream` and `Closeable` if you choose Stream resources.

If third-part AppConn want to achieve the {@code RefExportOperation}, it is necessary that the third-part AppConn
must upload the meta and resources of third-part AppConn job to Linkis BML at first, or packages the the meta and
resources of third-part AppConn job as a InputStream, then return the resourceMap to DSS.
@return a refJobContent related a only third appConn refJob
