Piotr Tabor c09aca1ba4 Split etcdctl into etcdctl (public API access) & etcdutl (direct surgery on files)
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/
