In the current doc, the command examples are like
"os server create" but the acutal command should
be started with "openstack" instead of "os", it
is misleading to first time users.

There was not a default IP version in "ip availability list"
command, if we used this command without "--ip-version" option,
the output was different from the outputs with the option
"--ip-version 4" and "--ip-version 6" and it is not right.
This patch add default IP version (default is 4) in ``ip
availability list`` command and make this command work properly
without ``--ip-version`` option. And also fix the help message.
