[Guojian Shao]

'project create' is missing '--parent <project>' argument in doc: http://docs.openstack.org/developer/python-openstackclient/command-objects/project.html#project-create

os project create
    [--domain <domain>]
    [--description <description>]
    [--enable | --disable]
    [--property <key=value>]
    <name>

Actually it is supported.
