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/
"snapshot" Restore/Status code was the only remaining dependency of client on 'server'
code. The code is solelly used by etcdctl. Long-term the snapshot code
should be migrated to 'etcdadm' style of tool such that we can
distinguish tool solelly depending on networking API vs. tools that
operation on etcd files directly.
We left snapshot.Save() code in clientv3.snapshot package, such that
clients can benefits from automated download&safe to file snapshot
functionality over the wire.
This change makes the etcd package compatible with the existing Go
ecosystem for module versioning.

This commit adds a new option --from-key to the command etcdctl role
grant-permission. If the option is passed, an open ended permission
will be granted to a role e.g. from start-key to any keys those are
larger than start-key.
Example:
$ ETCDCTL_API=3 bin/etcdctl --user root:p role grant r1 readwrite a b
$ ETCDCTL_API=3 bin/etcdctl --user root:p role grant --from-key r1 readwrite c
$ ETCDCTL_API=3 bin/etcdctl --user root:p role get r1
Role r1
KV Read:
[a, b) (prefix a)
[c, <open ended>
KV Write:
[a, b) (prefix a)
[c, <open ended>
Note that a closed parenthesis doesn't follow the above <open ended>
for indicating that the role has an open ended permission ("<open
ended>" is a valid range end).

Documentation was far too repetitive, making it a chore to read and
make changes. All commands are now organized by functionality and all
repetitive bits about return values and output are in a generalized
subsections.
etcdctl's output handling was missing a lot of commands. Similarly,
in many cases an output format could be given but fail to report
an error as expected.
