 * Starts a Koa server and listens on `port` or a randomly allocated port if none provided.
 * Enables CORS and body parsing by default. It's recommended to customize the CORS options
 * for production usage.
 *
 * If you need more control over your Koa server, you should avoid calling this function
 * and instead mount the router from your generated codes `createRouter` call directly
 * onto a server you have constructed.
