* For caddy v1 in our org

This RP changes all imports for caddyserver/caddy to coredns/caddy. This
is the v1 code of caddy.

For the coredns/caddy repo the following changes have been made:

* anything not needed by us is deleted
* all `telemetry` stuff is deleted
* all its import paths are also changed to point to coredns/caddy
* the v1 branch has been moved to the master branch
* a v1.1.0 tag has been added to signal the latest release

github.com/coredns is now also a coredns dep, this makes
github.com/coredns/caddy fit more natural in the list.

* cache: default to DNSSEC

This change does away with the DNS/DNSSEC distinction the cache
currently makes. Cache will always make coredns perform a DNSSEC query
and store that result. If a client just needs plain DNS, the DNSSEC
records are stripped from the response.

It should also be more memory efficient, because we store a reply once
and not one DNS and another for DNSSEC.
