Support docker 1.9 overlay networking

Docker 1.9 includes a new overlay network that uses consul as a storage backend. Since we already run consul on all nodes, we can hook docker into it.

this would be very useful if someone just wants to use docker, without any other overheads.
thanks

I guess then Calico will also be NOT needed for routing.

[stevendborrelli]

@navinSing We'll probably still need calico or another networking driver. Maybe we can have a chat later this week about the overall architecture and out plans.

Also, docker 1.9 has not been released by redhat's, so we're going to have to wait a bit.

Any ETA?

[stevendborrelli]

@kha0S with #1239 (merging this week), we'll be moving to Docker 1.10.x which will allow docker's networking. Once that is in we can look at the calico/docker integration.
