Motivation is as follows: - etcdctl we only depend on clientv3 APIs, no dependencies of bolt, backend, mvcc, file-layout - etcdctl can be officially supported across wide range of versions, while etcdutl is pretty specific to file format at particular version. it's step towards desired modules layout, documented in: https://etcd.io/docs/next/dev-internal/modules/
