Add release notes into coredns repo (#2645)

* Put release notes in notes subdir

Verbatim copy of the current set of notes on coredns.io. Copy them
here to make them authoritative.

'make sync' on the coredns.io site copies them back in. They need to be
formatted in Hugo style.

+
+CoreDNS-005 has been [released](https://github.com/coredns/coredns/releases/tag/v005)!
+
+CoreDNS is a DNS server that chains plugins, where each plugin implements a DNS feature.
+
+# What is New
+
+# Core
+
+A way to configure (external) plugin was added. Edit `plugin.cfg` and do a `go generate && go
+build` and your plugin has been added. This allows for out-of-tree plugin to be easily
+added. Documentation can be found in
+[plugin.cfg](https://github.com/coredns/coredns/blob/master/plugin.cfg).
+
+## Plugin improvements
+
+### New
+
+* *erratic*: a new plugin that can drop queries, limited in the current functionality, but useful for testing.
+* *trace*: a new plugin that implements OpenTracing-based tracing using Zipkin.
+
+### Improvements/changes
+
+* *proxy*: fix a bug when a connection hangs and never gets release (#467)
+* *proxy*: Fold *httpproxy* into it, which is now a normal proxy with a special `protocol`. For
+  Monitoring an extra label was added: `proxy_proto` that shows the protocol used (`dns` or `https_google`). 
+  See the [proxy README.md](https://github.com/coredns/coredns/blob/master/plugin/proxy/README.md) for details.
+* *httpproxy*: removed because functionality is moved to *proxy*.
+* *kubernetes*: Now implements the full
+  [Kubernetes DNS Specification](https://github.com/kubernetes/dns/blob/master/docs/specification.md),
+  including regular and headless services, endpoint hostnames, A, SRV, and PTR records.
+* *kubernetes*: Implements the `pod` type for requests in both a Kube-DNS compatible mode
+  (`insecure`) and a mode which validates that the IP in question belongs to a pod in the specified
+  namespace (`verified`)
+* *kubernetes*: Simplified the configuration of reverse zones. Instead of listing the zones in the
+  zone list, you can just add a list of CIDRs using the `cidrs` option.
+* *rewrite*: allow rewriting more bits of the incoming packet. This required some backward
+  *incompatible* changes, e.g. a new **FIELD** keyword is now required. See the 
+  [rewrite README.md](https://github.com/coredns/coredns/blob/master/plugin/rewrite/README.md) for details.
