Subject: [PATCH] Specify etcdctl version for livenessProbe

`--command-timeout` is supported in `ETCDCTL_API` version 3 and it is NOT supported in `ETCDCTL_API` version 2. Up to etcd 3.3 (inclusive) default version of `ETCDCTL_API` was 2. This change explicitly defines used `ETCDCTL_API` and allows usage of etcd versions below 3.4.
