    Fix pdns4 devstack plugin
    
    We no longer need to deal with xenial or older distro versions, so we
    can assume that we can always install pdns4 from the distro directly
    and don't need the distro version check any longer.
    
    Drop a config option that was removed in pdns 4.2.x.
    
    Use mysql credentials correctly.
