Arnaud Porterie 7d193ef1f3 Add builtin nodes discovery
Use `pkg/discovery` to provide nodes discovery between daemon instances.

The functionality is driven by two different command-line flags: the
experimental `--cluster-store` (previously `--kv-store`) and
`--cluster-advertise`. It can be used in two ways by interested
components:

1. Externally by calling the `/info` API and examining the cluster store
   field. The `pkg/discovery` package can then be used to hit the same
   endpoint and watch for appearing or disappearing nodes. That is the
   method that will for example be used by Swarm.
2. Internally by using the `Daemon.discoveryWatcher` instance. That is
   the method that will for example be used by libnetwork.
