Hot reload doesn't work correctly when middleware is changed

[ivan-varga-rs]

In version 0.15-beta1 when adding a custom middleware hot reload has issues - when middleware is changed all services get re-registered.

Current Behavior

Editing a middleware file re-registers services

Expected Behavior

Services don't multiply :)

Steps to Reproduce

1. Initialize a project with greeter etc
2. Add a custom middleware
3. Call greeter from repl -> get one response from service
4. Edit middleware file, wait for hot reload
5. Call greeter from repl -> get two responses from service
6. Edit again middleware again
7. Call greeter from repl -> get three responses from service
   

Reproduce code snippet

Middleware code:

`module.exports = function ExampleMiddleware(broker) {
const enabled = broker.options.hotReload; // or whatever

return {
	name: "HotRebuild",

	localAction(next, action) {
		return function (ctx) {
			console.log("Example example");

			return next(ctx);
		};
	},
};

};
`
