    Eliminate extra queries used to retrieve gw_ports

    The _get_sync_routers method was calling get_routers and
    then getting the gateway ports from the db in a separate
    get_ports call. This extra call is unnecessary since is
    already an SQL relationship directly between the router
    and it's gw_port.

    This patch eliminates all of the additional gw_port retrieval
    logic by replacing the get_routers call with a _get_collection
    call to make use of the gw_port object already present on
    each router object.
