Middleware after response about tsoa

[SwagiWagi]

I believe an AfterMiddleware decorator would be a great feature.
It's great for use cases such as:

1. Tracking the number of completed requests (for billing purposes for example).
2. Logging.
3. Disposing resources.

I believe it wouldn't be much work, I can make a PR for this.

I assume you are using Express,
there is two way to archive such feature.

1. custom template and make your own handler function,
   register every route with after middleware by yourself,
   details you can search on StackOverflow, I believe there is some example such as Call middleware after response sent in Express
2. tsoa indeed can provides such feature by including an AfterMiddleware decorator.
   but I doubt the necessity of it right now.

cc @WoH need your opinion.

(req, res, next) => {

  next()

  console.log('post')
}

Should do it, right?

	try {
	validatedArgs = templateService.getValidatedArgs({ args, request, response });
	{{#if ../../iocModule}}
	const container: IocContainer = typeof iocContainer === 'function' ? (iocContainer as IocContainerFactory)(request) : iocContainer;
	const controller: any = await container.get<{{../name}}>({{../name}});
	if (typeof controller['setStatus'] === 'function') {
	controller.setStatus(undefined);
	}
	{{else}}
	const controller = new {{../name}}();
	{{/if}}
	templateService.apiHandler({
	methodName: '{{name}}',
	controller,
	response,
	next,
	validatedArgs,
	successStatus: {{successStatus}},
	});
	} catch (err) {
	return next(err);
	}

Yes, just call next() in custom template, after L106 would work with after middleware.

Sorry to bring up a dead issue. But this doesn't appear to have been implemented.

I'm happy to do the PR if needed, or maybe there is discussion elsewhere as to why this wasn't added?
