/**
 * 构建服务器运行的包。
 * 1）服务器的包会使用webpack打包生产适用于生产运行的包。
 * 2）打包后会生成如下结构
 *      --[dist]
 *      ----[client]
 *      ------.js file
 *      ------.html file
 *      ----[server]
 *      ------.js file
 *      ------.html file
 *    [dist]由 path.resolve(workDir, outPath)确定
 *    [client]由 path.resolve(workDir, outPath, clientPath)确定
 *    [server]由 path.resolve(workDir, outPath, serverPath)确定
 * 3）打包完成后会生成在[dist][server]文件夹生成一个 [server.js] 文件(由serverEntryName参数指定名称)
 * 4）直接运行[server.js]文件即可启动服务器: $ node [dist][server][server.js]
 * @param {object} options {
 *     //options的配置详见 {./config/context}
 * }
 * @param cb 打包完成后的回调函数，如果没有则不执行 cb:()=>{}
