    Port data plane status extension implementation

    Implements the port data plane status extension. Third parties
    can report via Neutron API issues in the underlying data plane
    affecting connectivity from/to Neutron ports.

    Supported statuses:
      - None: no status being reported; default value
      - ACTIVE: all is up and running
      - DOWN: no traffic can flow from/to the Neutron port

    Setting attribute available to admin or any user with specific role
    (default role: data_plane_integrator).

    ML2 extension driver loaded on request via configuration:

      [ml2]
      extension_drivers = data_plane_status

    Related-Bug: #1575146

    DocImpact: users can get status of the underlying port data plane;
    attribute writable by admin users and users granted the
    'data-plane-integrator' role.
    APIImpact: port now has data_plane_status attr, set on port update

    Implements: blueprint port-data-plane-status
