By defining and using an proxy.Exchanger interface we make the proxy more generic and we can then fold back httproxy into proxy. This overrides #463 and #473 and should make futures extensions rather trivial * Add docs that talk about `protocol` and how to set it. * middleware/proxy: rename New to NewLookup It's used as a Lookup mechanism not as a completely new proxy, reflect that in the name. * Set maxfails to 3 by default when looking up names. Most of the changes have been copied from https://github.com/johnbelamaric/coredns/pull/1/files
