SSL certificate handling

[Aragur]

As far as I can see, there is no option to allow Traefik to generate it's SSL certificate automatically using f. e. a wildcard SSL cert using LetsEncrypt and the DNS API.

For now, seelf configures Traefik certificate resolvers with a TLS challenge.

This is the most straightforward way to get a valid certificate without messing too much with DNS configuration (requiring additional user manipulation).

But you're right and supporting DNS challenge could be a nice feature.
