* 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 Signed-off-by: Miek Gieben <miek@miek.nl> * Fix imports Signed-off-by: Miek Gieben <miek@miek.nl> * Group coredns/caddy with out plugins Signed-off-by: Miek Gieben <miek@miek.nl> * remove this file Signed-off-by: Miek Gieben <miek@miek.nl> * Relax import ordering github.com/coredns is now also a coredns dep, this makes github.com/coredns/caddy fit more natural in the list. Signed-off-by: Miek Gieben <miek@miek.nl> * Fix final import Signed-off-by: Miek Gieben <miek@miek.nl>
