Don't display non-tenant Floating IP in Floating IP project tab

Previously Floating IPs from all tenants are displayed when logged
in as a user with admin role and Neutron is enabled. Neutron API
returns resources from all tenants when the API is called with admin
role, so we need to call the API with additional filter parameter to
limit the results to a given tenant.

The referenced template was wrong, and the quota usages information
had not been switched to using limits.

Thanks to Nuno Santos and Rohan Kanade for the initial versions of
this patch.
