feat!: a few (important) changes

- move core configuratiion (authelia, traefik) to main .env
- move all hostname definitions to main .env
- add cloudflare ddns to automatically create DNS records
- automatically determine stremio addon hostnames for authelia using predefined hostname environment variables
- give all services a profile, including the previously implicit "default" services. Instead provide an explicit "required" profile that contains traefik and authelia. Allowing you to restart a specific profile without including the previous default services and also allowing you to have more control.
