Note env OS_PLACEMENT_API_VERSION support
The placement client (osc-placement) supports the ``OS_PLACEMENT_API_VERSION`` environment variable, but it is not described in the ``openstack -h`` command. So this patch adds the description as well as other environment variables. Change-Id: I41a3718bfa27ecf370c7375b4f761cda47866b1a
