    Update port bindings for master router

    An HA port needs to point to the correct host (where the master router
    is running) in order for L2Population to work.

    Hence, this patch introduces two fixes:
    * When a port owned by an HA router is up we make sure it points to the
      right node where the master is running, or a random node if there is
      no master yet (This corner case is fixed by the 2nd bullet point).

    * When a L3 agent reports it's hosting a master, we need to update the
      port binding to the host the master is now running on. This fixes
      both routers with no elected master (Yet) and failovers.
