Deprecate the unused quota_network_gateway parameter

The quota_network_gateway parameter was initially implemented as part
of the NVP plugin[1], which was later rebranded to vmware plugin[2] and
separated from neutron as NSX plugin.
However this parameter was later removed from NSX plugin[3] and is no
longer used.
