Title:
  [RFE] Strict minimum bandwidth support for tunnelled networks

Status in neutron:
  Fix Released

Bug description:
  This bug is related to
  https://bugs.launchpad.net/neutron/+bug/1578989.

  The aim of this RFE is to improve LP#1578989. This feature implemented
  all the code necessary to allow Neutron to report the available
  network resources. Neutron was responsible of retrieving the
  administrator configuration and send it to Placement. Each node would
  be represented as a resource provider; the ML2 agents would be child
  RP resources and the physical network would be child RPs of the ML2
  agents.

    RP host 1
    --> RP OVS agent
        --> physnet 1: egress BW, ingress BW

  This feature had a 1:1 representation of the physical networks
  available in each node (compute node). Each physical network had
  associated a physical device (a network interface) and this device had
  an associated egress and ingress bandwidth. We can see that as saying
  that "if we have a 10Gb NIC connected to physnet1, we'll assign those
  10Gb for ingress/egress".

  Currently we don't model the overlay networks (tunnelled networks).
  This is because there is no way to model the tunnelled networks. This
  RFE proposes to use a unique resource provider identifier to model the
  overlay networks in a host. Both in ML2/OVS and ML2/OVN (ML2/SR-IOV
  doesn't support tunnelled networks), the overlay traffic is sent to
  the "local_ip", that is the host IP address set on the local VTEP.

  This "tunnelled resource provider" inventory will be requested for any
  port min-bw QoS rule that belongs to a tunnelled network (VXLAN,
  Geneve).
