Bump to etcd 3.1.12 to pick up critical fix etcd [3.1.12](https://github.com/coreos/etcd/releases/tag/v3.1.12) (as well as 3.2.17 and 3.3.2) was released yesterday to fix a bug critical to kubernetes: Fix [mvcc "unsynced" watcher restore operation](https://github.com/coreos/etcd/pull/9297). - "unsynced" watcher is watcher that needs to be in sync with events that have happened. - That is, "unsynced" watcher is the slow watcher that was requested on old revision. - "unsynced" watcher restore operation was not correctly populating its underlying watcher group. - Which possibly causes [missing events from "unsynced" watchers](https://github.com/coreos/etcd/issues/9086). This will be backported to 1.9 as well. Release note: ```release-note Upgrade the default etcd server version to 3.1.12 to pick up critical etcd "mvcc "unsynced" watcher restore operation" fix. ``` cc @gyuho @wojtek-t @shyamjvs @timothysc @jdumars
