Discover the version number for a client in Administrator Guide wrong output of $ openstack --version

[Lujin Luo]

The correct output of running $ openstack --version is as follows
openstack 3.2.0

It'd be better if we add "openstack" before version number here to keep consistency with real CLI output.
