Public bug reported:

For a certain scenery, a tenant's max available bandwidth of floatingips
should be added to quota list.

Use cases
=========
In certain commercial scenery with neutron, such as some VNF cases using TECS of ZTE, admininstrator need to have previlege to limit the total egrees bandwidth of all floatingips belongs to a tenant, because of the physical network's expensive cost.  But for now, it is not allowed to limit bandwidth resource for certain tenant.

Now like below:
============
[root@localhost devstack]# neutron quota-update --tenant-id d9cc08fe87ee49f08020baa95893e2ef --floatingips-bandwidth 100000
Unrecognized attribute(s) 'floatingips_bandwidth'
Neutron server returns request_ids: ['req-2b534556-5c97-4c40-9f0e-5e488403cd1b']

I think it should be:
=====================
While the bandwidth quota is set, firstly this tenant's floatingip should be limited by QoS policy with qos-bandwidth-limit-rule referring to https://bugs.launchpad.net/neutron/+bug/1596611. Secondly, the sum of all floatingips bandwidth should not be greater than the quota configuration. This implementation will bring more usablity in commertail scenery for openstack.
