Correct a scheme example error from fake netutron versions client

Based on the standard neturon api document in following url:
http://developer.openstack.org/api-ref/networking/v2/index.html?expanded=list-api-versions-detail#api-versions
the response parameters from neutron api versions list request
doesn't have names of 'updated', 'version', 'min_version' which
nova api versions list has though. This patch is removing the
misleading and make the example explicit.
