Add network support to quota show

Currently quota show only lists quotas of Nova and Cinder, we
should make it also support Neutron resources. Also, Nova and
Neutron may have conflicts in the quotas of the following
resources: floating ip, security group and security group rule.
When Neutron is enabled, we should display the quotas of the
above resouces in Neutron, not Nova.
