Subject: [PATCH] Conditionally add www host to traefik router

If the domain_name entered contains subdomains, e.g. `api.example.com`
then do *not* add an additional `www.api.example.com` route to traefik

If the user enters only the domain `example.com` then add the optional
`www.example.com` Host to the traefik routers.
