Exclude particular path(s) from basicauth

You would have to add another router on the service.

- "traefik.http.routers.first.rule=Host(`my.site`)"
- "traefik.http.routers.first.middlewares=prod-auth"
- "traefik.http.middlewares.prod-auth.basicauth.users=test:$$apr1$$H6uskkkW$$IgXLP6ewTrSuBkTrqE8wj/'"
- "traefik.http.routers.second.rule(Host(`my.site`) && PathPrefix(`/api`))"
