Comment 3 for bug 1787793

VPN QoS is going to be implemented by Zhaobo during Stein https://review.openstack.org/#/c/558986/. But beyond this fact, if I understand correctly, the essence of this RFE is sharing a QoS bandwidth limit per tenant. Let's say the tenant has two floating IPs. The questions is how these floating IPs can share a tenant level QoS bandwidth limit. Some thoughts:

1) From the point of view of the API, we could associate a new attribute ('tenant_level' with values True or False, default False) to the QoS policy resource. When set to True, this attribute indicates that the policy is shared by the N-S traffic of the two tenant floating IPs

2) From the data plane of view the questions is how to set up such a shared QoS bandwidth limit so it is shared by these two floating IPs
