Adding errors middleware to Traefik

[darkstowner]

Is your feature request related to a problem?

It would be awesome to pass error codes such as 404 from traefik to another app/external service.

Describe the solution you'd like

Including the errors middleware in the config of the Traefik app with the option to input an ip or domain to redirect to in case no endpoint exists for that url.

Describe alternatives you've considered

For now the 404 pages only return an ascii page
