Scale-up functionality for etcd cluster * Set ETCD_INITIAL_CLUSTER_STATE from `new` to `existing`, because parameter `new` makes sense only on cluster assembly stage. * If cluster exists and current node is not a part of the cluster, add it with command `etcdctl add member name url`.

Use absolute path for etcdctl Small fix. The shell module won't automatically resolve the path to the etcdctl binary, so i prefixed with {{ bin_dir }}/ 2016-10-21 03:56:52 +08:00			`shell: "{{ bin_dir }}/etcdctl --peers={{ etcd_access_addresses }} cluster-health \| grep -q 'cluster is healthy'"`
