This patch adds support for QoS minimum bandwidth rules in tunnelled
networks. Now the ML2/OVS and ML2/OVN mechanism drivers can represent
in the Placement API the available bandwidth of the tunnelled networks
in each compute host.
Both mechanism drivers represent the compute VTEP (VXLAN) or TEP
(Geneve) interface as an IP address. This new resource provider
(by default called "rp_tunnelled") represents the available bandwidth
of this interface. Any new port created in a compute node that belongs
to a tunnelled network, will request to the Placement API the
corresponding bandwidth from the resource provider inventory.
This patch does not provide backend enforcement support for minimum
bandwidth rules.
