For the V3 API clients should access neutron directly for quota
information. The V3 API will no longer proxy quota related information for
neutron. Also novaclient will not get the quota information from neutron,
but users should use neutronclient or python-openstackclient instead.

The V3 API mode for novaclient will only be accessing Nova - with one big
exception for querying glance
so images can be specified by name. And longer term I think we need to
think about how we share client code amongst clients because I think there
will be more cases where its useful to access other servers so things can
be specified by name rather than UUID but we don't want to duplicate code
in the clients.
