[sqlalchemy-20] query.join should define one table/column per call

Browse Source 
The method ``get_router_for_floatingip`` query needs to define a join
clausule per table or column to be joined.

The expected query is the following one:
  SELECT DISTINCT routerports.router_id AS routerports_router_id,
  ipallocations.ip_address AS ipallocations_ip_address

  FROM routerports
    JOIN ports ON ports.id = routerports.port_id
    JOIN ipallocations ON ports.id = ipallocations.port_id
    JOIN ports AS gw_port ON gw_port.device_id = routerports.router_id

  WHERE ports.network_id = ?
    AND routerports.port_type IN (XXX)
    AND ipallocations.subnet_id = ?
    AND gw_port.network_id = ?
    AND gw_port.device_owner = ?

The goal is to retrieve the router that matches the GW IP, that is in
the same subnet and network as provided.
