Cluster Metadata Service using etcd
Run it on as many nodes as you like in your etcd cluster, and you will have a continuously up-to-date accounting of all nodes' metadata. Get it all by requesting /meta.
Each node discovers its own metadata and publishes that metadata to etcd every so often with a ttl of twice every so often. Every node watches all the nodes metadata keys and aggregates the results ready to be served via http.
