traefik dashboard changes

[Karsten Hassel]

Hi,

since traefik release v2.0.0-rc3 your dashboard setup is broken.

Replacing

- "traefik.http.services.traefik.loadbalancer.server.port=8080"

with

- "traefik.http.routers.traefik.service=api@internal"

works.

Thanks for the info. Fixed + tested with traefik v2.0.0-rc4.
