Kelsey Hightower b15806e189 etcdctl: update the ls subcommand help to match behavior
Currently the `etcdctl ls` subcommand help output is a bit misleading.
It mentions that using the `--recursive` flag will output all keys and
values for a given path:

    --recursive  returns all values for key and child keys

This is inaccurate. The `--recursive` will only output the key names
under the given path. Fix the issue by updating the help string for
the `--recursive` flag.

    --recursive  returns all key names recursively for the given path

Fixes #2379.
