Abstract the caddy call and make it simpler. See #3261 for some part of the discussion. Go from: ~~~ go func init() { caddy.RegisterPlugin("any", caddy.Plugin{ ServerType: "dns", Action: setup, }) } ~~~ To: ~~~ go func init() { plugin.Register("any", setup) } ~~~ This requires some external documents in coredns.io to be updated as well; the old way still works, so it's backwards compatible.
