    ctdb-eventscripts: CTDB_NATGW_PUBLIC_* optional on slave-only nodes
    
    Commit 4ee4925d416a86341bd76c11fa99ec9173682a1d forgot about
    CTDB_NATGW_SLAVE_ONLY so it introduces an incorrect failure when this
    is set, and CTDB_NATGW_PUBLIC_IFACE or CTDB_NATGW_PUBLIC_IP is unset.
    
    Relax the sanity check to see if CTDB_NATGW_SLAVE_ONLY is set.
    
    Update the documentation to explicitly state that
    CTDB_NATGW_PUBLIC_IFACE and CTDB_NATGW_PUBLIC_IP are optional and
    unused if CTDB_NATGW_SLAVE_ONLY is set.  It would be possible to
    insist that CTDB_NATGW_PUBLIC_IFACE and CTDB_NATGW_PUBLIC_IFACE should
    be unset in that case.  However, it is more reasonable to allow
    consistent configuration across nodes except with some nodes
    configured slave-only.
    
    Add tests, update infrastructure and fix a thinko in the stub's
    "natgwlist" implementation.
