Put the network UI and overlay docs in separate files

.. and link to them separately. They are different features.

+# Native Multi-host networking
+
+There is a lot to talk about the native multi-host networking and the `overlay` driver that makes it happen. The technical details are documented under https://github.com/docker/libnetwork/blob/master/docs/overlay.md.
+Using the above experimental UI `docker network`, `docker service` and `--publish-service`, the user can exercise the power of multi-host networking.
+
+Since `network` and `service` objects are globally significant, this feature requires distributed states provided by the `libkv` project.
+Using `libkv`, the user can plug any of the supported Key-Value store (such as consul, etcd or zookeeper).
+User can specify the Key-Value store of choice using the `--kv-store` daemon flag, which takes configuration value of format `PROVIDER:URL`, where
+`PROVIDER` is the name of the Key-Value store (such as consul, etcd or zookeeper) and
+`URL` is the url to reach the Key-Value store.
+Example : `docker -d --kv-store=consul:localhost:8500`
