Currently only Express.js is used as the default SSR HTTP server. More HTTP servers will be available if they:

• load the generated SSR app server render bundle
• load server-hooks config from generated app bundle
• put server logic in server hooks and wrap them as a server hook plugin
• create HookLifeCycle instance using loaded server-hooks config and custom server hook plugin
• pass HTTP Request to HookLifeCycle and send HTTP Response with the result

More http server like koa.js, nest.js could be implemented.
