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`.

set "check_mode: no" for read-only "shell" steps that registers result "shell" step doesn't support check mode, which currently leads to failures, when Ansible is being run in check mode (because Ansible doesn't run command, assuming that command might have effect, and no "rc" or "output" is registered). Setting "check_mode: no" allows to run those "shell" commands in check mode (which is safe, because those shell commands doesn't have side effects). 2017-02-06 18:13:21 +00:00			`check_mode: no`
