[RFE] Allow shared resource providers for physical and tunnelled networks

[Rodolfo Alonso]

This RFE is an extension of https://bugs.launchpad.net/neutron/+bug/1991965.

The goal of this RFE is to allow to share the same resource provider for one physical network and the tunnelled networks. This is a very common deployment configuration: there is one physical network and one device connected to this physical network bridge. This is used both for the VLAN tagged traffic (physical network) and as VTEP/TEP for the tunnelled traffic. In this configuration, the resource provider used for the physical network (e.g.: br-ex), must be shared with the tunnelled traffic.

    Allow shared resources between physical and tunnelled networks

    Since [1] it is possible to create resource providers for tunnelled
    networks and model the available bandwidth for overlay networks.

    In some deployments, the admin uses the same physical network interface
    for a physical network and the tunnelled networks. In that case it is
    complicated to correctly split the bandwidth between the inventories
    of the resource providers. This patch adds the ability to create a
    resource provider with traits of both the physical network and the
    tunnelled networks. E.g.:

      $ openstack resource provider trait list $brex
      +----------------------------------+
      | name |
      +----------------------------------+
      | CUSTOM_NETWORK_TUNNEL_PROVIDER |
      | CUSTOM_PHYSNET_PUBLIC |
      | ... |
      +----------------------------------+

    With this resource provider, a request comming from a port in the
    physical network or an overlay network is provided by the same
    inventory.

    What is missing and will be added in next patches:
    * Tempest tests, that will be pushed to the corresponding repository.
