Fix ssl configuration

This is suggested, and also obviously needed to make the file provider
work in order to set certificate configs. The reason is, that traefiks
file provider seems not to work with our docker provider rules within
the traefik.toml and instead throws erros becase of undefined characters.
This is the easiest approach to get it working.
