Creates a proxy middleware which proxies the given route to the given port.
Useful for plugins which start their own servers but should be accessible
via the main Vendure url.

*Example*

```ts
// Example usage in the `configuration` method of a VendurePlugin.
// Imagine that we have started a Node server on port 5678
// running some service which we want to access via the `/my-plugin/`
// route of the main Vendure server.
@VendurePlugin({
  configuration: (config: Required<VendureConfig>) => {
      config.apiOptions.middleware.push({
          handler: createProxyHandler({
              label: 'Admin UI',
              route: 'my-plugin',
              port: 5678,
          }),
          route: 'my-plugin',
      });
      return config;
  }
})
export class MyPlugin {}
```
