Service discovery using etcd

[Paxton]

Fedback
Allow using etcd or similar for service discovery instead of Docker linking. Gaudi would need to implement some kind of sidekick script that announces container's connectivity details e.g. IP & Port.

Thanks for the feedback.
Yes, it's in the next steps of gaudi to use etcd to link containers together.

It will change a lots of things in the build process, it'll integrate it in a futur version
