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/
release-3.5

of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed

You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
