Redo DNS configuration (#2034)

this commit changes and streamlines the dns_config into a new
key, dns. It removes a combination of outdates and incompatible
configuration options that made it easy to confuse what headscale
could and could not do, or what to expect from ones configuration.

- MagicDNS domains no longer contain usernames []()
- This is in preperation to fix Headscales implementation of tags which currently does not correctly remove the link between a tagged device and a user. As tagged devices will not have a user, this will require a change to the DNS generation, removing the username, see [#1369](https://github.com/juanfont/headscale/issues/1369) for more information.
- `use_username_in_magic_dns` can be used to turn this behaviour on again, but note that this option _will be removed_ when tags are fixed.
- This option brings Headscales behaviour in line with Tailscale.
- dns.base_domain can no longer be the same as (or part of) server_url.
- This option brings Headscales behaviour in line with Tailscale.
- YAML files are no longer supported for headscale policy. [#1792](https://github.com/juanfont/headscale/pull/1792)
- HuJSON is now the only supported format for policy.
- DNS configuration has been restructured [#2034](https://github.com/juanfont/headscale/pull/2034)
- Please review the new [config-example.yaml](./config-example.yaml) for the new structure.
