Etcd initial pass

Switch to using ETCD recommended by @shawnps  for more flexible configuration management,
I could write a helper script that imports from the YAML file to bootstrap people?  I thought the choice of ETCD let people write whatever they want so I thought an easy example would nice (etcdctl is so easy, so is curl) . In our case I want a way to easily update etcd manually to bootstrap this whole thing. Next I would like to write something that watches AWS and updates etcd based on AWS meta tagging.  Let me know, happy to change whatever.  I think now it's super flexible and generic.
