This is a giant cleanup of the etcd code. The earlier version was written when I was less experienced with golang. This is still not perfect, and does contain some races, but at least it's a decent base to start from. The automatic elastic clustering should be considered an experimental feature. If you need a more battle-tested cluster, then you should manage etcd manually and point mgmt at your existing cluster.
