Ingresses for named servers don't match link (trailing slash)

[remche]

Bug description

When using named servers, we are redirected to http://host.tld/user/username/test but corresponding ingress rule path is set to /user/username/test/.
Although it's not an issue for ingress-nginx, this remains controversial for some other (most ?) controllers (traefik/traefik#5159) which do not deal with the trailing slash and will fail to route to the named server.

Expected behaviour

Make URL (redirection and control panel link) and ingress rule path match exactly.

Your personal set up

k8s with traefik 2.0.6.

Note: I cant reproduce it with traefik 2.2...
